Great place - vast, high ceilings, filled with light and superbly appointed.
Amazing location right in the heart of Condesa.
It is right on one of the main thoroughfares of the area, and you do feel this, particularly during the day when the windows are open. But the two bedrooms at the rear are pretty quiet at night and the front bedroom is actually largely ok too as the owner has installed double glazing for precisely this reason.
Sergio was an extremely accommodating host, being very flexible despite us messing around a couple of times with dates and he also very kindly offered us the sizeable monthly discount rate despite us booking in two separate blocks, which made the apartment feel good value. it felt like nothing was too much trouble.
A maid comes for several hours a day but I suspect you could just tell Sergio if you don't think you need this.
All in all a great host and a great place to stay.
