We stayed at Mario's place for a family easter trip to Porto, and I truly hope it hasn't been the last time there! His place is perfect: in the city center, very nice and clean rooms, welcome drink and all sort of helpful tips (maps, app etc), spacious (we were 6 people, but even with 2 or 3 more it'd still be ok!). We felt perfectly comfortable! I can warmly recommand this place! Thank you very much Mario!!!
