We had a great stay. Lots of restaurants around, and very close to everything. Mario was very responsive and the app was very helpful. We would definately come back to Porto, and to Mario's appartment if avaliable. Just a note to those ones that are travelling with friends or new couples: The bathroom does not have a door, just a curtain, so you can hear everything. We didn't mind, but it might be a problen for other people.
