I spent 4 days in Mexico City, and I couldn't have chosen a better place to stay than this. I didn't meet Héctor and Karen in person, but the self-check in and check out were straightforward and uncomplicated, I always received clear instructions from my hosts, and they always replied to my messages withing few minutes.
The apartment is exactly like it looks in the pictures, furnished and decorated in a stylish vintage way, with a comfortable bed, a sparkling clean bathroom, and a well-equipped kitchen. The neighbourhood is very safe, green, and walkable (La Condesa is a very nice suburb of mexico City), close to Parque de España and a stone's throw away from the metro station Chimpalcingo, from which you have a great connections to all downtown CDMX attractions (rides are cheap, fast and frequent).
There are plenty of reastaurants, eateries, groecery stores and corner shops in the neighbourhood.
If you are lucky enough to find this place available, go ahead and book it!
