This is an awesome place and Raul is an awesome host. The apartment is pretty centrally located and in a safe area. The place is clean, decorated in a cool way, and feels very spacious. The rooftop is great and such a cool place to just relax at the end of the day. Only things I would point out are that the apartment is three flights of stairs up and that the hot water lasts long enough for two medium length showers before it needs time to heat up again. Raul was very proactive and communicative. He answered my questions very rapidly and was very kind. Definitely would recommend this place when visiting Porto.
