Echoing all the reviews here, this place is just perfect. Clean, super comfortable, very well equipped, great location, and the incredible view from the balcony is exceptional. Hosts are very welcoming, friendly and communicative. The flat is in the top floor so there are stairs to climb, but if you're coming to Porto you should expect to climb a lot in any case so it's part of the experience. The flat is perfect for a couple, we had a fantastic time and really hope to be back.
