I stayed here during one of the conference and other than it being a huge place, there is nothing that stood out. There was a 2 days event which I was attending and I arrived at 10, even though they had the room ready and available, they wouldn’t let me check in earlier, demanded 25€ extra if I did so I said no and went to work in one of the restaurants waiting for the event to begin. I had a hand carry luggage with me and I enquired if I can atleast leave my luggage which was also not available. So I am not sure why I paid for a basic room at 147 € but had services that was missing the customer part of it .
