Luis is a wonderful host, always available and helpful ! He welcomed us even when we arrived late at night, and we had a very pleasant discussion with him as he told us about his flat, the building and recomend us many good places to go and things to do in porto ! We hadn't much time to visit the city so the location was really perfect for us, on a very nice little place just at the heart of everything ! And to finish with the best, Luis flat is very design, cosy and super clean ! We couldn't find a better place to stay, that's why i highly recomend it :)
