This place was great! It is very central, very close to both the train and metro. The apartment is stocked with everything you might want if you would like to eat in. The outlook over the square is also really nice from both the dining/lounge and the bedrooms. Be warned that this is at the top of a few flights of stairs, but we found the rises quite gradual and the staircase reasonably wide. If you are looking for a place in Porto you would be hard pressed to find anywhere better.
