The most important things I want in an Airbnb are that it's safe, quiet, and convenient, and this apartment checked all three boxes. I stayed for two weeks in June and overall enjoyed it.
Easy walking distance to many great restaurants and bars. I like that it is equally easy to walk to Av. Amsterdam as well as all the spots in Roma Norte. Kitchen was well stocked. The windows seal very well and block out all noise from the street. I had no noise while sleeping (the apartment above me was also vacant at the time). Note that the windows both tilt and swing open, depending which way you turn the handle. The windows facing the other apartment in the dining room and kitchen may only be tilted, for privacy reasons.
The apartment is located near where three streets intersect, and there's a little triangular park outside. Very good coffee shops nearby too: Quentin and Paradigma.
The bed was comfortable and there's a huge walk-in closet section. The furniture is a bit old-fashioned, but it's exactly as pictured so it wasn't a surprise. The bathroom sink hot and cold water faucets are on opposite sides of the sink, so you have to kind of mix the water with your hands while washing.
The main drawback for me was that there's not a lot of natural light in the dining room where I worked from home every day, due to the shape of the building. If you work from home all day, you might want to go out to coffee shops or co-working spaces, or the roof (if it's also available when you're there).
Mariana was helpful and responsive as a host.
