The appartment of Luisa was very nice. It was really big and really clean. I really enjoyed the days at it and like all the small cafe's around it and the little walk (5 minutes) to the beach. The metro station is just around the corner, but luisa will give you so many usefull tipps, that it's not neccessary to drive by metro in the city. I will book the appartment aggain for my next trip to porto.
