We had a great time staying at Kleber and Glaucia's place. Although we arrived late check-in worked fine. We were welcomed by a friend of the hosts, who was very nice and gave us many recommendations. The room is small, but really has everything you will need. The best thing about the appartement is the location, you are near the city center and you can walk nearly everywhere by foot. There is no elevator in the building and the place at the 5th floor, so that is something to consider. Other than that I would highly recommend to stay here when visiting Lissabon.
