Incredible location with beautiful balcony overlooking the bridge. The building itself is (very) old, and it is a one-floor walkup, if you're concerned about carrying your suitcase. But the apartment itself is very modern, and the host left the kitchen very well stocked with essentials, and a few frills. The smaller bedroom is just big enough for the bed, which basically goes wall to wall, with a couple of feet extra at foot of the bed. The location is very very quiet at night. During the day there is some construction noise, but that did not go to the back, where the bedrooms are, and did not really bother us. One thing to note: The hall connecting the living/dining/bathroom in the front and the bedrooms in the back has about a 5'4" ceiling, so if you're taller than that, you have to duck every time you walk through. The apartment has all the modern conveniences, and the wifi was fine. The location is a short walk from Sao Bento train station and the cathedral, and a little farther but still walkable distance to much else in Porto. Note that the "street" where the apartment is located is basically a narrow, dead end street that is very hard to drive. I don't know if taxi/uber drivers will do it. But you can get dropped off at the end of the street, right at the cathedral, and then walk three or four minutes to the apartment.
