There were odd shortcomings in the room: no towel racks, no refrigerator, and (contrary to the photo) the bed was too big for the room, making walking past it a one-way street at the base of the bed. The TV was in an odd off-center location, perhaps because a person walking at the base of the bed would hit their head on it otherwise. The elevators are small and antiquated; it's easy not to notice that the elevator has arrived because there is just a little light -- one has to open the elevator door manually.
One bright spot: the breakfast was excellent. And the hotel is on the tram line, for those who like to use public transit. Indeed, access to some type of transit is necessary because the hotel is not walking distance from anything of tourist interest in Porto or Vila Nova da Gaia.
