This is a great place for one person to stay. The roof is a nice place to relax when it is sunny and the location is no more than a 10-minute walk from Chapultepec Park and the metro station that is there. La Condesa is a lively part of the city and plenty of restaurants as well as some bars are walking distance of the apartment.
There are a good number of steps to climb to reach the apartment, and the room itself has no closet. Be aware of that if bringing certain kinds of clothing.
