I had a great stay at Jorges place. The appartment is very small, but for me as a solo traveller it was perfect. Everything was clean and the standard is good. It is located close to the old town and the centre of the city, and many good places to grab a meal near by. The best is the view over the Douro-river from the balcony, on sunny mornings it is absolutly stunning!
I would gladly come back for another stay!
