I stayed here for 2 nights and everything was fine. The place is close to the city centre and you have a lot of bars and restaurants around. Amelia answered our questions immediately and the communication was very good and also her son was very friendly. In the room you have everything you need and we were there with two people and this was enough space for both of us.
I can recommend the place if you search for a good stay in Porto.
Obrigada Maria Amelia!
