In my opinion Hilton is just about the worst hotel brand out there. I actively refuse to stay there at any opportunity. They wanted to charge me 10 euros to use the gym when I stayed in one recently (this was a discounted rate as well because I'm a member of Hilton Honours), regular price for guests was 20 euros. For one use of the gym!! That's not far off what I pay for a month of 24/7 gym access at home.

Wifi was 25eu a day. A small bottle of water from the mini bar was 8 euros, a small coke 12 euros. A pretty average chicken ceasar salad from the restaurant was 35 euros. It's just crazy when you/your company are already paying 350 euros a night for a room.
