I was in Lisbona for 3 nights. The apartment is in an a perfect area. You can move by metro and most of the tourist area are walking distance. Carlos was kind and he helped me when I needed it. In the apartment there are no windows in the communal space, the light is turning on as you pass through. I shared the bathroom with other two rooms, I would prefer to have something to clean immediately, cause sometimes it was not that clean after the others used it. The smell of the apartment is not of cleaned. But I think it's also cause the bathroom and the communal area can't be refresh by windows.
Anyway Barrio Alto is the best area to live the night life in Lisbona and this apt is a good chance if you're a student or a young couple. It's a really safe area and always full of people.
