The communication with Juan Carlos, who was hosting us during our stay, was very good and quick both before and during our stay. It made our vacation a lot more relaxed, flat wise we didn't have to worry about anything. He also organized a taxi ride from and to the airport beforehand so we got there without any issues.
The flat is in the fourth floor and the staircase leading to the flat is quite narrow, for us this was not a problem but it is something to keep in mind. Otherwise, the flat was really nice and clean and we had all the space we needed for two people. The basic essentials needed for a stay were all there and having the washing machine was quite handy.
We had a great time staying there! :)
