We had a pleasant stay in the heart of Condesa.
Pros:
Great location, as in GREAT! Large bed. Good wifi. Gas heated water, so warm showers. Clean. Kind and commutative hosts.
Cons:
The apartment is a bit dark. The bedroom faces the street, in street level, so bring earplugs if you are a light sleeper. Limited kitchen utensils, but I would recommend to explore the restaurants in the neighbourhood anyway.
