There was no flexibility regarding the check-in hour (3 PM was under no circumstances negociable). After arriving at the indicated pick-up point for the keys, I got the error message that the code was incorrect. I tried to call Loic, but the call center dropped the call after a minute. I sent a message and I got a reply after half an hour that the pick up point was moved very far away from where I was supposed to get the keys. So without any warning I had to go to a different location, which wasn't even clear where exactly it is.
After losing 90 minutes in this "treasure hunt" for the keys, I finally got to find them.
Besides this, I asked for a hairs dryer, but again, that wasn't possible either.
All the rest was as described. But because of the check-in issue, my family and I were left extremely disappointed of the wrong and hard communication.
