The flat is really cosy and clean, very charming and my far at all from all the shops and restaurant. The area is quiet, the street is very typical and the few neighbours we met were very friendly. We were welcomed by Maria's daughter who gave us some addresses to have dinner. We had some food prepared for the next morning and I thought that was really thoughtful!!
Lisbon is a great city, very romantic. Just one recommendation: bring a pair of good shoes!! ;)
