The apartment was really spectacular to stay in. Large, open spaces in all rooms. We had some initial problems opening the code box to get the key, but one of the hosts really did her best to help us through phone, and was even ready to send someone out in case the code box would not have opened. It turned out it had stuck in some way, so that's definitely something that has to be checked for future stays.
It would have been nice if the description of the apartment included the information that there were 4,5 floors up to the apartment, no elevator. This can be quite tough if you have a large suit case, or have mobility issues. I would also have been nice to have an explanation of how the key to the door worked, since it was so special. It took a while for us to figure out how it should be entered into the door.
But in all, Kim and his team were very good hosts, the apartment was really nice and spatious and we enjoyed our stay!
