Wonderful use of space in a great part of town. Myself and a girlfriend were only in Porto for 3 action packed days but found the location to be brilliant (20 minute walk from the city centre, which we did everyday).
The place was spotlessly clean on our arrival and the bed proved super comfortable.
There is a great cocktail and pizza place open until late just down the road (Terraplana Cafe) that has an outdoor area and lots of board games that was a firm favourite with us pre or post dinner.
Communication with Pedro and João was brilliant. Nothing was too much trouble, so if you're in need of ideas of things to do or see before you arrive then do not hesitate to ask!
Needless to say I would be delighted to stay in future on my return to Porto.
