A touch of design is not enough..
I spent 3 nights in this apartment and I can say that the location is great to visit the City. You can easily reach every place by public transports or cheap taxis and Condesa (one of the coolest areas) is few minutes far.
Andrés is very kind but we had some little misunderstanding: the check-in at 4pm is a little bit unconfortable if you arrive after a long travel (and it is not possible to anticipate it), and we received the hairdryer and some clean towels only the night before leaving. Finally, in the house there is a terrible smell of damp (probably coming from the sink ) which makes quite unpleasant to stay at home.
