Nice place, clean safe and nice proximity to public transportation (train station 5min walk). Centralized location relative to the city. Only items to consider is 3rd floor (the degree sign denotes the floor), also pretty busy road directly in front of the main entrance, so if road noise bothers you make sure to close the window or request a room on the opposite side. Very hospitable, great response times, and feedback about what to do, and I would recommend this place. Pack light and enjoy Porto!
