Good communication and clear instructions from host to enter the apartment, the neighborhood is nice with few bars and restaurants at reasonable price nearby, internet access was OK and also near subway stations and very close to downtown and interest points (So, I used public transportation all the time, it is close to downtown but not to go walking). I went with my family and in general was fine, the apartment was small for 4 persons, but just like the pictures, so no expecting something different.
Only complain, is that had a smell of mood or humidity that was a bit unpleasant.
