We really enjoyed our stay. The apartment is modern and well decorated. The location is absolutely perfect for exploring the city on foot (we didn’t need to take a taxi or the metro at all during our stay). I would note that the “house rules” indicated that the apartment is in a quiet area so there is to be no noise past 10 p.m. but from our experience the neighbourhood was not particularly quiet; the apartment is on a rather busy street full of tourists at most times of the day. This was not a negative but just not what we were expecting. Additionally, our upstairs neighbour was unfortunately very loud until about 4 a.m. each night (I believe the upstairs unit is a rental as well so this would not necessarily be the same). But overall we had a great time and really loved Porto!
