The location is perfect, within walking distance of every attraction in Lisbon. Moisés is constantly there making sure the place is tidy and well kept, and asked about how my stay was going several times, he is very kind and even booked me the taxi to the airport. We had some time to chat and he is very nice and fun to talk to. He was very helpful when telling me about Lisbons attractions and provided me with a map and marked up for me, which was great.
The bathrooms and common spaces are cleaned and tidied every day, which is always a great advantage.
I would recommend this room if you are traveling with someone, however, being a woman traveling alone I did have some reserves about the street. Had no safety issues at all though. And you are two blocks away from Martin Moniz, which is always lively.
