Sebastien met us at the house late in the evening on time, showed us how to use the keys for different doors, showed us the apartments. Yes, you have to walk up to the 4th floor, but we were able to do it :) Sebastien told us about a bakery with delicious pastries.
There was no hair dryer, but we discussed this issue beforehand, so we were prepared. There was also no kettle, but you can use a ladle to heat water. The bedclothes were a bit worn, so there was a peculiar smell, but they were clean, as were the towels. The batteries did not heat, but we quickly figured out how to turn it on, so the apartment was warm enough. Very conveniently left at 6 am without bothering the owner.
Thank you for your hospitality!
