Our stay in Nuno's apartment was for one night, on a short notice. The apartment was nice, clean, the location is pretty good, though there are strange people in the area, so take care with the pockets and bags. More about the location, is very close to the center, and downstairs you have a very popular place for fado lovers.
Communication was ok-ish, as Nuno responds a bit late and we had to wait for his messages, however, when he responded he was very nice, he offered all the details. The check-in was done very easy, Nuno sent us the instructions on how to get in.
