Gonzalo's place is an excellent value. It is located 2 blocks from the subway, a few blocks from Chapultepec park, grocery store ( Soriana) and pharmacy, and Condesa.
Gonzalo Is a wonderful host. He welcomed us, provided info and maps, and quickly responded to our enquiries.
The apartment is part of a 3-story complex with 2 buildings facing each other. Gonzalo's apartment is on the ground floor at the back facing another apartment. It is therefore very quiet, away from street noise. The drawback is that there is no direct sunlight. The building is new, very modern, spacious and clean with the basics for cooking. The bed is very comfortable with plenty of closet space.
We had a very good, comfortable stay and felt very secure. The vigilantes were very nice and helpful too.
