Nuno's place is in an excellent location, just outside of the city center. It was clean and well furnished, and Nuno really went the extra mile to get us checked in and comfortable. The only other thing I would add is that the location is a little loud. It's right near the metro so you will hear the trains go by in the evening and night. The road outside is also cobblestone so you hear every car that goes by. This didn't bother us personally, as we are all heavy sleepers. But those who aren't should keep these factors in mind.
