We were in the apartment with 5 persons for 4 nights and it was really comfortable. The house is big, updated and very clean. It has all the things you need. The location is perfect as it is located near the main square.
Marcia is a very good host. She greeted us very warmly, answered quickly to questions and left a handy local guide with her favourite places.
The apartment is perfect for multiple couples. Very nice stay in Lisbon!
