We had a wonderful stay at Marco's place. We didn't meet him, but his mother in law Cassilda was there to receive us. She was wonderful and gave us a lot of tips. The communication the rest of the time was super good. The water boiler was broken, and we got a replacement before we even got back to the apartment.
The place is just as in the photos. There's everything one could need, including a washing machine. There are restaurants just outside the building and a grocery shop in front of it. Walking distance to many nice places.
We loved Porto and we really enjoyed staying in this apartment, super recommended!
