I thoroughly enjoyed my stay at Eugenia and Luis's apartment. The apartment itself couldn't be in a better location - right in the city centre near some of the key landmarks/sights (Cathedral, Dom Luís I Bridge, markets). It is very comfortable and homely, and the apartment I stayed in was very spacious and comfortable with all the possible amenities one would require provided. Because the floors are all wooden floorboards there is a bit of noise when the other apartments above/nearby are occupied, but this one only a concern on one of the nights I stayed. The check in process was extremely smooth and streamlined with friendly staff to show you to your room and a complimentary offering of Port. I met Eugenia as I was leaving who is a lovely, friendly person. I recommend asking her about the history of the building, as I found it quite interesting. Overall I couldn't recommend staying here enough and I would certainly stay again if I ever visited Porto in the future!
