This a place to stay in Porto!
It's 25 min from the centre, so if you like walking, it is the right place. I've spend 4 days there and was walking 10-20 km. per day.
Host communication is just perfect (in a minute) with all recommendations what to do!
The only thing what could happen wrong is that you can hear everything through the door, but all my neighbors were quiet, so no problem.
My suggestion to visit Ribeira Square restaurant, Praca da Ribeira No16, 4050-513 Porto for superb food, place and desert (main dish, desert, wine, coffe - 25 Eur). As the totally different place to eat (funny to visit) Novo Mondo (small local restaurant, if you can call it so:), cheep to eat (menu - 5-6 Eur).
