Really great location, close to all the central sights in Lisbon including the Elevador Santa Justa and tram 28.
Bit of a walk to get to and steep stairs so bear in mind if you have difficulty with mobility.
Flat itself is very nice and has a lovely view. Walls are a bit thin, so recommend earplugs if you are a light sleeper.
We had a great time and would stay there again. Thank you Pedro and Claudia!
