We stayed for a month in the apartment. The apartment is just like in the pictures, and very functional. We loved the apartment's location, near bakeries, a supermarket, the subway, and in between neighborhoods that were fun to explore (and not in the high tourist concentrations of the old town). The apartment had everything we needed, and we cooked quite a bit.
We stayed during an extreme heat wave, and it required some skills to keep the apartment cool. (There is one A/C in the living room but it's not enough for the whole apartment.)
Rafael and Tania were very responsive when questions or needs came up. In particular, on our very last night, an emergency came up and Rafael came at 1 am to help. Gracias Rafael!!!
