This is a good value, budget, option which is less well-maintained than the photos would suggest. In particular, plug sockets were either falling out of the wall or non-functioning, shower badly limescaled and only working on one setting, and areas of the walls unplastered. Kitchen equipment is limited and not great quality. There was street noise at night and at times this affected sleep. However - it does the job just fine if you want a self-catering option in a very central location in Porto - we really loved the area which is close to loads of fantastic restaurants and shops. With a bit of additional TLC it would be a very comfortable place to stay.
