If you are looking for a great central location and a clean , cozy spacious apt. then Maria's place in perfect. She made sure we knew how to get in the main door and where to get the keys. It is on the top floor of a very lively street but the noice canceling windows and doors made sleeping at night comfortable. The AC worked great and she has a wonderful well thought out book with everything you need to know for adventuring in Lisbon. We would stay there again during our next visit to Lisbon.
