I couldn’t meet Nuno but he and his colleagues were very kind and helpful with quick responses. The room and the view from the window were so beautiful, which made me feel like a local. About location, it only takes about 5 mins from Martim Moniz metro station. if you are girls, you might think it’s a little bit dark at night in the neighborhood but overall it’s safe. I would definitely recommend this Nuno’s apartment:)
