I had a wonderful time while I was staying at Pensão Rosinha. Although I had the room without a window, it was okay for me, because I read about it before. And in the first night, we could leave the door open to the next room. Also there is a fantastic living room and a nice kitchen, where you can spend your time.
The whole apartment was clean and very comfortable.
I met Paulo & Camila only for a few minutes the evening before I was leaving, but they seemed to be some very nice people. Instead I was warmly welcome by Nuno, who showed me everything and gave me some good recommendations for Lisbon and especially for the nice neighbourhood. Thanks! :-)
I would definitely recommend this place.
