Rita and Gustavo were wonderful. After finding the flat, they gave us a very useful custom guide to the city, as well as a huge list of restaurants in every price range that they recommend. The flat itself is beautiful and located in a perfect area for exploring Alfama and downtown.
They were also very responsive. Several days after our stay we returned to Lisbon and checked if they had availability. They were booked, but still offered to help us out with restaurant reservations if we needed. Awesome people.
