We had a great stay for two nights in a room in Marine's apartment. The host was very responsive and flexible, and the space was incredibly clean and functional. Especially the kitchen was very well equipped, so it was a shame we couldn't stay for longer. Doing laundry was also very easy. The location is a bit outside of the main part of the city, but if you plan well there are multiple (4) bus lines that get you to the center in about 30 minutes that are only a few minutes away from the apartment. Recommended to enjoy a few days in beautiful Porto!
