We stayed at Franciscos place for one weekend. The apartment is very close to the center and the metro, and has some really sweet tipical portuguese Cafés nearby. Francisco put a lot of effort and love in the decoration of the place and you can really see and feel it, it's a really sweet apartment. The communication with him was perfect and very friendly, the check-in very uncomplicated since Francisco put a keybox with code on the door, so you can let yourself in. Since the apartment is on the Ground Floor of a main road with plenty of cars, it tends to be a little noisy, which was fine for us, since we stayed only a couple of days and spend our hours mostly walking around beautiful Porto. Since it is a very old house and there is only one window that you can open (direction main road) it sometimes seems a little musty, but here again: to us, it was ok. For a weekend trip the tiny apartment is well located and low budget.
