Ana's place in Lisbon was very clean, and looked exactly as described and shown in pictures. We liked the communication, the check in process was automatic and fast, and we got quick replies whenever we had a question. In addition to all this, it is in an excellent location near a nice square, two metro stations, and a lot of shops and restaurants.
The slightly negative aspects: I felt a bit claustrophobic because there was not too much light (due to small windows) and the slanted roof above the bed is not something I liked too much. Moreover, the staircase to the apartment is very narrow and steep, so going up with a very heavy suitcase was tiring. Also, the shower is very very small. But if you don't mind all this, I would definitely recommend the place.
