I was not pleased entirely by the apartment and I am pretty sure it could be improved in the future by the host.
First, I contacted her the day before taking off to Mexico city, I didn't receive any answer from her. The day of the departure either. When we arrived (my gf and I), the guard didn't let us enter inside because they didn't receive any request from the host. We tried several times to contact her via social media and finally we were able to enter the flat after 1 hour or so. The host was not around to help us with these issues. Then, we wanted to connect to the wifi… no wifi… we contacted her, but the communication was very parse and we waited a long time for answers (she just ignored the message at the end), same with the TV that was not working… so for the whole stay (10 days) we didn't get any internet connection, I needed to buy a simcard with internet and we couldn't watch TV. Airbnb is getting like that, host does not care about anything and accept money without any care during the stay. I was expecting better for this place and from the host, more communication and at least that she checked before if everything was working before leaving the place.
Apart from this, the district of Polanco is nice, the flat is close to Mall and Soumaya museum, that's nice and 10 minutes to subway. The bathroom was a bit small but I don't really care about that. There is a swimming pool and a nice rooftop that can be very nice to chill. The receptionist woman at the entrance was very nice and helpful and it was a pleasure to deal with her.
