We had a great time in Porto and a warm welcome with many useful tips for the city thanks to Alex from ORM. It was possible to drop luggage already at 11:30 (when normal Check-In is 17pm). The communication with ORM was excellent during our whole stay. The apartment is perfectly located for a short stay in Porto when you want to live central and have everything in walking distance. You can hear neighbours / what happens on the floor through the wall so if you have a light sleep this might be a little minus.
