I was staying at Juan's apartment with a group of friends. The location of the apartment is perfect: there are lots of shops and restaurants very close and it is also very easy to go to the airport as buses there leave basically next door.
Juan is a great host - he responds quickly and is very helpful and flexible. We had one part of the big apartment for the first night for five people and could then extend and have the whole big apartment for eleven people for the rest of the weekend. Juan also arranged late check-out for us.
The only misunderstanding we had was about the total payment - there were some taxes and extra fees as we were checking in at 8 pm.
Overall, it was a great experience and I can really recommend Juan's place!
