It's a lovely place very well located (Alfama is best of Lisbon) and as all other guests say, the terrace is a huge bonus! There's a lot of stairs but that's normal in the area. There's no locker outside for the keys, so if you arrive late they'll be an extra charge (I paid EUR 35 for arriving at 12:15am). Other than that and the issues in the bathroom (damp, constant bad smell, and a leak you need to take care of by emptying the plastic container at least once a day - I went in August 2020, hopefully it'll get fixed), our stay was great.
