Lovely flat in central Porto, close enough to the river but also high enough that you don't feel you're constantly walking up hills! Perfect for a long weekend for two. Go2oporto were incredibly helpful and accommodating, arranging both early check in and late check out as well as coming to the rescue when we had a problem with the lock. Would just make sure that locking and unlocking the bottom door from the inside and outside is explained fully before they leave, as it's quite a difficult door!!
