We really enjoyed our stay in the apartment. The location is great with the metro stop accoss the road. There are plenty of cafe, shops restaurants in the area. Communication was excellent. The apartment was very comfortable. The balcony was a real bonus. As mentioned by others the floor boards are noisy so if you are a light sleeper it might be disturbe your sleep if the apartment above is up late. But it didn't bother us. Apart from that it is very quiet at night. Would definitely stay again if I was in porto.
