We stayed four nights in Rodrigo and Ana's apartment and absolutely loved it. Not only does it look fantastic but everything was very comfortable and very well designed, great bed, furniture, well equipped kitchenette, etc.. It's very centrally located but far enough away from the nightlife and crowds. There is some city traffic on the street below, but we thoroughly enjoyed opening all the windows and just relaxing in the incredible space while enjoying the phenomenal Lisbon weather (before convincing ourselves we should head out for dinner). Rodrigo and Ana were also both very accommodating and the tips they provided were great. We'd absolutely recommend this place and stay here again.
