Our stay at Sofia place was very nice! she was really kind and even though we didn't meet, she always got in touch with us to know if everything was ok, and to give us some advices and an helpful list about what to do in Porto. Her mother, who stay in the house, was thoughtful too.
The house was ancient and charming as mentioned in the description, it was in the city centre, fifteen minutes walking from the Ribeira area and the main monuments of the city.
