This is an amazing aparment! We stayed for three nights and it was a very good choice. The rooms are very spacious, clean and comfortable. Sonia, who greeted us and gave us they keys, also gave us some food and sights recommendations, which were great. The rowing club has a bar, where you can eat, but also a small cocktail stand in front of it over the weekends. So you can take a nice drink and enjoy it upstairs on a rooftop terrace, which has the best view of Porto. And this is definitely the biggest advantage of this apartment.
It is located by a main street, so it might get loud over the weekend, but somehow we were not disturbed by that.
