Nuno's apartment was great and Nuno, himself, is very communicative and was able to make the check-in process incredibly smooth. He added a lot of small touches to the apartment (converters, dishwashing soap and washing machine detergent) to make the stay more comfortable. The view is spectacular and just as you see in the pictures.
The only downside is that there is construction going on during the day, and since the apartment is above a hostel and in an alleyway with active nightlife, there is not a lot of peace and quiet. The first night we arrived, the bars closed at around 2a (we were there during the weekdays) and the hammering/construction started promptly at 8a. The triple-pained windows did a lot to help the street noise, but can't help the construction going on nextdoor. If you aren't bothered by the noise this is a great apartment, but probably best for a younger crowd.
