This apartment is very nice and gave us a welcoming and a nice feeling. As a family of 7 people, with two elderly and 2 children, everybody had their space. The location is excellent and you are a minute away from the dazzling life and action of Lisbon, witch is amazing. The apartment is in an old building and that is the feeling you are seeking after, but be aware that it is not very isolated, sound wise, so new years eve and the days after, we did not sleep much since we were attending all the parties in the neighborhood :)
But would stay here again, and since we have all fallen in love with Lisbon, it is very likely.
