I stayed in Teresa ' place for 3 night with my boyfriend. It was a perfect place to visit Lisbon from, pretty much walking everwhere. You can also take the trams that are passing just down in the street. The place is a large studio, white and clean. We met Teresa when we checked in quickly and she was very gracious. She was coming in just to do the check in before going back to work so we did not have time to hang out much.
Also, we had a car and having a garage in the center of town was a big plus for us! Good choice if you want to visit and enjoy beautiful Lisbon!
