We had a wonderful stay at Erica's place. The room is located on the top of a beautiful house in the very centre of Coyoacán. We were very positively surprised about the place, better than we expected (from the picture). Because you're on top of the roof in an area with loads of trees and have your private spacious terrace, it's like an oasis of tranquillity - you really don't feel in the centre of a megacity.
The room isn't big but because it's efficiently furnished and with the terrace in front of it, it doesn't feel small.
All in all, highly recomendable :-) !
