Great apartment in a beautiful area, which is not too touristic. The apartment was very clean and Nail is a very friendly an thoughtful host who provided us with everything we needed (including milk and cookies at our late arrival)!
Campo di ourique is an authentic area. The planes fly by quite closely, but the isolation in the flat is very good, so this doesn't really bother.
We came to Lisbon with kids and enjoyed our stay very much. The heating was appreciated.
