In the bustling heart of Buenos Aires, Casa Calma Hotel is a hidden eco-oasis. Opened in 2008, this boutique hotel was specifically envisioned by the Argentine architecture firm *Plural Arquitectos* to serve as a literal deep breath of fresh air amidst the heavy city traffic.
Its most striking feature hits you the second you walk through the door: a massive, two-story vertical garden. This lush wall of living plants naturally filters the air and provides a stunning, organic centerpiece for the lobby, instantly signaling that you are stepping out of the concrete jungle.
Sustainability is baked right into the building’s DNA. The architects prioritized renewable materials, installing gorgeous bamboo flooring throughout and implementing a strict zero-plastic policy. Even the external walls are designed to maximize natural light while keeping the interior perfectly insulated from the city heat.
To top off the wellness theme, every room comes equipped with its own private jacuzzi, and the hotel offers a 24-hour honesty bar stocked with organic snacks. Guests can also grab one of their signature bamboo bicycles to explore the historic nearby streets of Retiro completely carbon-free.
Expert reviews
“This wellness hotel in the heart of downtown Buenos Aires has taken the concept of in-house spa to a new level, equipping each of its 17 rooms with jetted tubs.”
Featured as Fodor’s Choice in Buenos Aires.
“Hidden behind a living wall of greenery is this ecoconscious hideaway in central BA. The 17 rooms are pristine and relaxing with Jacuzzi baths and a serene ambience; some have small balconies.”

Reasonable stay, but would not book again
Good location, good breakfast
Front door is always locked and can only be opened by staff member from inside - very inconvenient
WiFi is very inconsistent, sometimes would disappear for hours
Shower cabin is old, seals falling off

Amazing medialunas, lovely staff but not the treat that we were looking for.
The staff were very friendly and made us feel so welcome. The linen was clean and fresh, and the room decor cheery and bright. The medialunas at breakfast were absolutely delicious.
It was noisy at night even with all doors shut. The door to the room wasn't sound proof and next to the lift so we could hear other guests coming and going directly outside our door. The jacuzzi was so furious and noisy, and it required so much water that I was worried it would fall through the floor! It wasn't exactly the romantic final night in BA that we imagined.

It’s nowhere near as nice as the rating makes you believe.
Good location, staff were friendly and tried hard to fix the problems with the property but they couldn’t, it really does need some money spent on it
We ended up reducing our time here as the hotel was a bit of a dump and the noise from the old busted AC compressors outside the windows made it too loud to sleep without earplugs. The shower door in 602 didn’t close so water went all over the floor, there’s mould on the shower ceilings and the overall standard wasn’t as clean as it should have been. The staff were good and tried to move us but the overwhelming smell of marijuana on level two and the significant noise from a more broken AC unit had us running back upstairs before eventually finding somewhere else to stay.

Decent hotel, great location!
The location was perfect.
The breakfast was not included and was not to our liking. Our sauna was broken and the bath items were an extra charge. We also had to pay for a coffee pod in the room!

Overall a nice experience
Everything functioned, sauna, jacuzzi, and shower, fridge, all good. The comforter bed sheet had a small stain but overall the room was well cleaned. A little noisy at night but there was some sound proofing for the room. Front desk staff were available 24/7 and were very friendly.

Fantastic stay! Will recommend.
Amenities, location, staff, jacuzzi, price.
Had issues with some of the facilities but staff managed to address them. No massive issue apart from the shower glass door as not closing properly.

The perfect hotel for a calm and relaxing evening in the jacuzzi after a day of adventurous sightseeing in Buenos Aires.
The design is very thoughtful and detailed, minimalist. Cozy and pleasant for traveling with family or friends.
I would highlight the professional, attentive, and friendly service at the reception. They gave us excellent recommendations for lunch, such as the Croque Madame restaurant at the Palacio Paz. It is very well located for touring the city center.

Highly recommended hotel at good location with large rooms and friendly staff
Very nice hotel at a good location. It is not a big hotel, which is nice. Extremely friendly and helpful staff; rooms are large and well equipped; breakfast was somewhat limited, but it had all that I need for breakfast.
Nothing really

I had an exceptional experience during my stay at the hotel. Its prime location right in the heart of the city, surrounded by important attractions and conveniently close to transportation hubs, made my trip even more enjoyable.
One aspect that truly stood out was the hotel staff. Their level of service was nothing short of amazing. They were attentive to our needs and went above and beyond to ensure our comfort. Their wealth of suggestions for local activities and places to visit greatly enriched our stay, making it truly memorable. Their excellent communication skills made us feel valued and well taken care of.
And let's not forget the breakfast! It was an absolute delight. The wide variety of options catered to every palate, and the quality of the food was top-notch. Starting the day with such a delicious meal was indeed a treat.
