This place is dirty and grimmy and all the better for it. it just oozes character. the bridges across the Douro are fantastic, as are the Port Wine lodges on the opposite bank. The centre is a bit of a maze in places and well planned in others. Well worth a visit, it offers a nice break from cities that are orientated just towards tourists and i geniunly feels like a city that is full alive (ik sorry abit of a cliche there to end with!!)
