I stayed at Luis' apartment with seven friends. The apartment looks exactly like the pictures, was clean and has a great location. Also the contact with Luis and Patricia was perfect.
The downfalls are that the apartment is really noisy. The apartment had wooden floors and every morning at 8.00AM the church bells next to the apartment starts ringing very very load. And the apartment has only one bathroom for eight people and the toilet doesn't flush that well.
But besides that we enjoyed our stay at the apartment.
