Maria's apartment is beautiful, charming and spacious for a couple. The views from the kitchen and the bedroom are gorgeous. Location is excellent in Barrio Alto, almost at the top neighboring Príncipe Real. Now, it is very important to note, Barrio Alto is buzzing with bars and restaurants, people like to hang out on the street and is part of the folklore, so yes, it can be noisy (windows open) on weekends, fortunately the apartment has excellent noise isolating windows that worked pretty well. We did not interact with Maria much as she was away, but instructions to get in were easy and the apartment was clean upon arrival, so for us that had been in Lisbon before, Maria's place was the perfect spot.
