We had an amazing stay at Bruno's B&B. Beautiful, clean, modern room with all possible facilities. The historical center is only a 10 minute walk away (across the beautiful bridge of Porto) and the B&B had a patio with a great view over the city (we had a very lovely breakfast there). Bruno really made us feel at home and gave us great tips about the city (sightseeing, restaurants). All in all I would really recommend this place!
