Upon arrival we said we would stay 1 to 2 nights. We had to pay €39.50, the son mentioned €10.00 administration costs. I asked his mother how much an overnight stay cost, her answer was €29.50 which is also stated on their site. After 1 night we decided to leave and I thought I would get €10.00 back. The lady was suddenly less friendly and even said that administration costs had never been discussed. In short, never stay there.
