We had a positive experience. The apartment was clean and seemed to be newly renovated. Upon arrival we were greeted by Eva, a manager, who was very friendly and helpful. Eva was also quick in responding when we contacted her throughout our stay and booked a shuttle for us to the airport (€22). The location of the apartment is excellent: in the city centre close to the Liberty square and Sao Bento train station as well as several major attractions. With regards to sleep quality, the beds and the bedding were very comfortable, but we found it to be quite noisy at night: there was music playing all throughout the night and you could hear the beat even through ear plugs.
