Everything was exactly like the post said and even better.
The apartment, which they keep as clean as a hotel, is recently renovated. The furniture is new in excellent conditions, with a great taste and a very cozy touch. It feels like a wonderful home.
Everything worked wonderfully and it had more appliances than necessary of the best quality, there even was a beautiful brochure made for us to move around with ease.
The area is very close to many city highlights and it is amazing to just walk around. There are delicious restaurants, beautiful coffee shops and fun bars and yet the street, where the apartment is at, is very peaceful and quiet.
The host, Andres, and the team in charge of administrating the apartment are very nice people and comunícate clearly and proactively which made it easy to check in and out. They even touched base often with us to check if everything was fine with our stay, eventhough everything is pretty self explanatory within the apartment.
I highly recommend this place. Mexico City is amazing, Polanco a wonderful area and the apartment everything I expect and much more.
