Everything looks fine but ..
when I arrived with standard-two-person room reservation, they proposed the ground floor room with the floor more than 1.5m underground on the window side. A small window near the ceiling only. But with a big TV in prison like room. After discussion the staff offered another room but 10Eur per day more. I accepted the deal. An afterwards:
The staff claims for money the next day day after the deal and not at the moment we are checking out. They prefer cache. Althow, afrer coversation, they accepted a card. But the admistration managed to authorize the transaction without my pin-code. There is no way to add your dinner price to room totals... cache immediately. No cards accepted.
For us, Russuans, it looks like washing money.
