This is a great AirBnb. It has an excellent location that is walkable to some great bars, restaurants, and clubs. If you are spending most of your time in Condesa and Roma Norte, it is VERY walkable.
If you are exploring outside of these neighborhoods, transport is close. Truthfully, we still walked mostly when visiting Rosa, Juarez, Chapultepec, and Doctores as well.
About the space: the space was perfectly appointed for everything you could need. It was a decent size, nice private patio and nice upper deck. I will say, you can hear the street and neighbors in the space. If you are a light sleeper, I would suggest bringing earplugs. Also, if you are showering or using the bathroom, you can hear everything so not a lot of privacy if you are staying more than just one guest. This didn't bother us, but privacy is important to some and thought it was worth noting.
Juan Carlos and Thomas were both very prompt and efficient in their responses. Check in was very smooth. They even helped take care of securing a taxi for our ride back to the airport. They are incredible hosts. Great place and great hosts!
