We booked the apartment last minute due to missing our flight. The location is only one metro stop away from the airport. Apartment is situated in a quite residential area and only one block away from the metro station to connect you to anything you want to see in Lisbon. Even though we only stayed one night with Teresa's, her apartment is very well cared for, nicely decorated and has a very inviting feel. The bedroom we stayed in was very comfortable and clean. Communication was great and she was home to let us in and give a tour of the apartment. She is very friendly and provided breakfast for us in the morning :)
Highly recommended!
