we thoroughly enjoyed our stay at Mario and Ana's apartment!! Mario met us to check in and had some great tips for places to go. we soon realized that we were very close (walking distance) to many of the places that we wanted to see in Porto, and a very short walk to the river and Dom Luis bridge! the apartment was very clean, true to the pictures, and had everything we needed. the fan in the bedroom kept us comfortable at night. the apartment is up 3 flights of stairs, which although were no issue to us, I imagine would be more difficult for someone with mobility limitations. we would definitely stay here again if we return to Porto!
