Me and my family visited porto in april and had a nice time at Rui's apartment. Although we were a litte late there was no problem with the check-in.
In the apartment were some stuff like cereals, milk, shampoo und shower gel for free use. There were also some extra blankets if someone's getting cold. In the area of the flat is everything you need like a bakery or a supermarket.
Most of the time we walked into the old city center by foot which lasts about 30 minutes.

Everything was fine and we enjoyed our time in Porto.
