Me, my boyfriend and 2 friends had a good time at Mario's apartment. The apartment is exactly as the photos, very clean and confortable and the airconditioning was very nice. It works perfectly for 4 people. The better part is the location, very central and in a very nice neighborhoud, easy to walk to the city center, with bars and restaurants near by.
The only downside was the lack of basic ingredients for cooking, because we only stayed for 3 nights and was not rentable for buying them, and also the lack of hot water for bathing, this one we believe was an occasional problem. Furthermore, i recommend Mario's apartment.
