Hotel Mosaic House, Prague

Odborů 278/4, 120 00 Nové Město, Czech Republic (show on map)

Hotel Mosaic House is a stunning design hotel located in the heart of Prague, housed in a functionalist building that dates back to 1934. Originally constructed as a trade union headquarters, it once served as a hub for workers, featuring a large theatre hall for education and entertainment. Today, the hotel thoughtfully preserves its rich heritage, including original mosaic details that have been carefully restored and showcased with modern lighting.

The property is celebrated for its commitment to sustainability, acting as a green urban oasis long before it became a standard industry practice. Its eco-friendly design includes sophisticated systems for recycling greywater, energy-efficient recuperation, and a lush, green courtyard garden that offers a quiet escape from the city’s busy streets.

Indoors, the atmosphere is bright and artistic, blending contemporary boutique sensibilities with historical architecture. Guests can enjoy a private wellness spa complete with a sauna and Jacuzzi, or relax in Café Mosaic, which occupies the building’s former theatre hall. For those seeking the best views, the hotel’s penthouse suites offer terraces with sweeping panoramas of Prague’s rooftops and the iconic castle.

The hotel is perfectly positioned for exploring the “City of a Thousand Spires.” It is just a short walk from major landmarks like the Dancing House and the historic New Town Hall. Whether you are wandering through the charming streets of the Old Town or taking a stroll along the Vltava River, the location provides an ideal base for experiencing the best of Prague’s cultural and architectural wonders.

Expert reviews

Lonely Planet review:

“A blend of four-star hotel and boutique hostel, Mosaic House is a cornucopia of designer detail, from the original 1930s mosaic in the entrance hall to the silver spray-painted tree branches used as clothes racks.”

We had a wonderful stay at Mosaic, thanks to its excellent central location and accommodating staff.

My friend and I thoroughly enjoyed our stay at Mosaic. The hotel is in an excellent central location, with most of the attractions, restaurants, and activities we wanted to visit within easy walking distance. Although breakfast was not included in our booking, we chose to have breakfast in the hotel’s café every day and were very impressed with both the quality and service. My friend has dietary allergies, and the staff were extremely accommodating and attentive to his needs throughout our stay.

The room was well designed, comfortable, and exceptionally quiet, which made for a very relaxing stay despite the central location. Overall, we had a wonderful experience and would happily stay here again.

The only minor point was the size of the single beds. My friend is over six feet tall and found them a little short for his height, so taller guests may find them slightly less comfortable. Aside from this, we had a very pleasant stay.

Very comfortable week long stay, we were made to feel very welcome.

The location was quiet but it was not far to walk to the river and all places of interest. Very friendly staff, good food and quality furnishings in well designed room. The room was actually better than it looks in the pictures. Efficient taxi service to the airport.

Breakfast could be crowded at certain times but was very good. Bar food was also excellent. We were disappointed when we found out that the restaurant shut on a Sunday night as we were planning to go back for the fourth time.

Great location, great staff and comfortable

Excellent staff who were always helpful. Breakfast was very good with great selection.

The only issue we had was with the temperature in the room no 509. We could not get temperature below 23C for the whole stay even with the windows fully open, even leaving them open all day did not help. Staff tried helping but AC not in use as temperature needed to be 18C outside. So did not have good sleep. Bed and bedding was very good, just the temperature in the room.

Quirky hotel would highly recommend it.

Central location, very quiet, lovely bar area, good variety for breakfast and clean.

Air conditioning difficult to navigate, cosy room but large balcony made up for it.

I would stay again!!!

The breakfast was amazing...truly! The bar/lounge area was sooo perfect! Great service, great food, great wine and so very comfy. A great place to wait for someone or meet and hang out. Also used it after we checked out to wait for our ride to airport. The spa we used for 2 hours just for a warm tub, shower, cold plunge and sauna. What a great idea! Only about $100...perfect after we checked out of our room to spend time before our flight.

I loved our terrace room but its configuration was weird...the L shape provided some space but the hangars and coffee were at the end of it...meant we had to trip over suitcases and each other to go there...it was not very functional. Should have been luggage racks to elevate more than one suitcase...the desk and basket like hassock were in the way...a comfy chair, luggage rack and small table for coffee would have been better. Loved the terrace!

A perfect stay with exceptional service, attention to detail, and a genuinely welcoming atmosphere.

Everything was exactly what we wanted — every fine detail had been carefully thought through and dealt with. The staff were incredibly lovely, attentive, and went above and beyond to cater to all our needs throughout the stay. The whole experience felt seamless and relaxing from start to finish. We would highly recommend this hotel and would definitely return.

Great hotel very close to the city centre

Very well designed hotel with comfortable beds. While the rooms are not very big, they are comfortable and have everything you need, including a comfortable bed. The breakfast buffet is also excellent

Wonderful, would stay again.

The location was great and easy enough to walk to everything. We stayed 3 days, the hotel itself is charming, as are the rooms. Our room even had a tub, that my 6’2” man fit into.
Lovely little garden to sit it, tons of books, welcome drink, personalized greeting. Water bottles, coffee, tea, hot water kettle, fridge.
Comfy beds and plenty of pillows.

Downside is the parking, however we found a backyard court 1/2 block away that let us park there for a fee. But I like that better than valet parking off site.

Brilliant city break, beautiful hotel, great staff.

Smelled lovely upon arrival, staff were attentive and decor was beautiful. Good size and well maintained bathroom. Great location too, a short 15 min walk to the centre.

We were on level 6, the room was a little hot and the aircon didn’t seem too effective but we just opened a window out onto our balcony.

Lovely place to stay while enjoying beautiful Prague.

Great breakfast, love the Secret Garden to hang out it, the rooms were nice and comfortable and of course location can't be beat.

Two comments here - as an early riser the ability to grab a coffee in the Secret Garden before breakfast started would have been much appreciated. Second, shower pressure very poor.

All in all the room was fantastic. Great light, confortable beds, great bath products. A place to return.

The location, the mood of the hotel, very trendy and with a fresh vibe. The lounge, bar and library full of life. People having a drink, reading, chatting and/or planning about their day or working at their laptops.

My daughter lost a cardigan in the way between the elevator and our room (during the night) and no one returned it… it was sad and bad luck!

Care for everything and everyone

We received a warm welcome. It was clear that detail matters, especially the care of guests and our overall impact where a lot of thought has been given. Loved the creativity, the library and seeing the birds on the roof garden in the morning.

Having to leave.

Cozy. Incredible. Everything needed provided. Highly recommend.

Not in crowded place, but close enough to old town. Also, I am very strict with the cleanliness and this hotel was at my high standards with that.

Beautiful and stunning hotel with brilliant facilities and a good location

Brilliant location! Loved the rooms! Lovely design, good amount of space, lovely products, and a well stocked mini bar for a decent price per item. The blackout shutters were brilliant. Daily room service. Overall, beautiful rooms!

Breakfast was also lovely! There were baked beans which is always a plus as a British group however, my only complaint is there was no potato based item at breakfast (like a potato rosti or hash brown) but this is a small thing. Overall, brilliant breakfast with a good variety.

The hotel was absolutely stunning and beautifully designed. We loved the facilities and made good use of the spa! We hired it out privately for a group of 7 and it came to about £11pp. There was a jacuzzi, cold shower, sauna, relaxation room, changing rooms with toilets and shower, and complementary drinks! It was brilliant. I would highly recommend!

Amazing birthday trip

The design of the hotel is amazing. The staff was very helpful and friendly. The entire room was very generous, with an amazing view. The bed and the pillows were extremely comfortable. The water that they brought us every morning was a big plus :) we travelled in February and it was a bit cold in the room, but the staff helped us increase the temperature in the room and everything was perfect.

Nothing. Everything was great!

The rugs in the room were super slippery
