I stayed one week in Lisbon. All was fine, a small remark on the room, no windows and no wifi signal, and the noise made by other people, but that's not Paulo and Isabel's fault, which was sometimes annoying. Also not so dramatic but I wanted to mention it. Part of this, all was fine, location is great, appartement is well decorated and clean. Advises given for food and bars was really nice and recommended. On a global note I was happy with the stay.
