Mario was a great host, even though we didn't meet he made sure to check in regularly before and during my stay (24 our reception is very convenient). The apartment is in an ideal location for exploring the hip areas of the city, in the heart of Condesa and near Roma. It is very spacious, nicely decorated and clean. The only thing that may be an issue for some, is that it can get quite noisy due to the people and music on the street (I was there Friday and Saturday night), but not a big deal. Overall I highly recommend Mario's place!
