We had a bad experience checking in. One day prior to arrival I noticed that the booking was for one rather than two people. This was for a four (4) night stay, not just overnight.
On arrival, were were told we needed to pay an additional 300 euro, almost the same amount as the entire stay of 4 nights. The clerk then contacted the supervisor. The amount was changed to an additional 208 euro. Our travel mood was spoiled, we felt we were being overcharged.
