I have visited Lisbon every summer for the past four years and often stay for one or two months at a time on writing fellowships. Principe Real is one of my favorite neighborhoods and Rita's apartment is in the best location. You are central to everything: the Principe Real park, tons of bars and restaurants, the Miradoura Alcantara, and little produce markets, but you are on a small, peaceful, almost hidden street. The apartment itself is probably the best airbnb I've ever stayed in while in Lisbon. The light around 5pm is stunning, the whole place is open and spacious, the tiles in the kitchen and bathroom are charming. We were lucky enough to have this apartment for over 2 weeks, and we had many lovely dinners and got so much writing done. Rita met us our first day and brought us typical Portuguese egg pastries as a welcoming gift. She offered suggestions, but since we knew Lisbon relatively well, was only too happy to give us our space and independence. I can't recommend this place enough.
