Excellent location, in the midst of a lively area of Condesa and easy walking to Roma. Though it sits above several popular bars hosting live music, noise was not an issue. The bedroom is very quiet -- but even in the main rooms with windows we really didn't have an issue with noise. Cute apartment, well appointed.
Matias was great. Our flight changed after booking everything and we ended up arriving at the apartment rental at 1am. At that late hour, Matias promptly met us at the door carrying a five-gallon bottle filled with purified water for our stay.
