The apartment is really good located close to big supermarket and some restaurants, easy to explore Polanco on foot and Mexico by Uber, but be ready to traffic jams. As for downsides: it is really very noisy even during the day because there is no isolation, but we have experienced some road works during the night, so it was absolutely not possible to have a sleep. Some cupboards are broken and outlets are not working, as well as lighting in the kitchen. I think this is the problem everywhere in Mexico city with water pressure in bathrooms.
Nevertheless Zaide is really very nice host, always communicative, ready to help and easy to find a decision in any situation.
