I did not have the pleasure of meeting Pedro in person (only in written form), but his answers were always very polite, accurate, quick, and full of kindness. When I got to the place, his girlfriend, Filipa, welcomed me in a similar way: kind, friendly, and gave me clear directions upon arrival and also when I text messaged her with questions.
There are no complains: the place is very well connected to Porto via metro or walking, the house is quiet, clean, and all you need is at your disposal. This is, by far, an excellent choice if you are visiting Porto.
