We had a fantastic weekend at Sofia's house. The house is just like the pictures, clean and cosy. Very close to Porto central locations (walking distance). Sofia was very helpful at our arrival, giving us in a perfect French directions and nice plans for lunch, dinner and other enjoyable visits.
The only negative point of the weekend was the neighbour on the second floor who knocked at the door at 6pm to repeat (and not with a very friendly attitude) what we already knew and respected: no noise (even when climbing the stairs to go the bedrooms!)
