The host was very hospitable with us and he was also available giving us his phone number to contact him, if necessary. The studio is exactly as the photos so we did not have any surprise about that.
Besides that, the other positive things in the studio was the wi-fi connection always fast and stable, and the shower which is pretty good. In addition, it is located in a high floor and it has a beautiful view for Andes. At last, the host sent us an pdf which contains good tips of the city.
About the negative side, we thought that the neighborhood is not so safe, especially at night. The streets are usually deserted and not walking friendly. So if you want to enjoy night life or arrive a little later, it's better use a taxi.
Furthermore, there were household items far from good. The bathroom had just grimy towels. We had to buy new ones. The bed linen was pretty tight and it did not fit into a double bed. The pillows were uncomfortable. In short, we would suggest to you take with you your own personal household items or we would suggest to the host to take care of this.
And finally, as the studio is located underneath the terrace, the parties really annoyed us into the night at the weekend.
