Nuno is the best host you can imagine. We were very late at check in, almost 1am but it wasn't a problem for him. Although it was late, he stayed to give us some tips for sightseeing, restaurants, bars... We followed his suggestions and had a great time, we ate great tipical portugese food in lovely restaurants, not so "touristic" ones, where you pay a lot for not so good dish.
He gave us directions for each point of interest and he was available for any information or any kind of help during our stay in his apartment and even later when we moved to another property.
