The check-in and check-out process was very easy - Samuel was at the apartment at the arranged time with the key. He also gave a lot of recommendations for places to get good food and some of the local sights.
The location of this apartment is amazing - just a block away from the main cathedral. It's on the first floor and the stairs that lead up to it are easy to climb (there is also a lift if you need it). The kitchen has everything you would need and the bed is very comfortable.
