We had a great stay in Porto also thanks to the very warm welcome of Raul, who had very helpful hints for us concerning his hometown, the most important sights, good places to eat etc. The flat is also awesome. Well equipped with a wonderful terrace and view over the city and the river. And there is a bakery next door, so best possibilities for having pasteis de nata every morning.. ;) All in all: go there; you'll have a very good time!
