This apartment is ideally located in a quiet part of La Condesa, in walking distance (or a cheap Uber ride) to many of the city's main attractions. Every suggestion of Sylvia's that we tried was great. You will find them all listed in a handy pamphlet upon arrival. We especially liked the casual restaurant a block away (Alipus).
The apartment exceeded our expectations...it is a very cool space with unique architectural features. The apartment was impeccably clean. The doormen were very friendly and on duty 24 hrs per day. They were even glad to hold our bags on our final day after checkout while we visited the nearby Museum of Anthropology. They were more than deserving of a nice tip for this service and for accommodating us as guests of the building in general.
This was as professional a vacation rental experience as I've ever had. Whenever we go back to Mexico City, we will definitely try to stay here again.
