The worst Hilton ever
This is the worst Hilton I have ever been and one of the most unpleasant hotel experiences in general (if I take out of the equation "motel 6" and similar.
It started with the check in
I was the only one checking in at that time. There were 3 clerks at the reception, 2 women and one man. One of the women was busy with a very big folder, the man looked at me as I was invisible so i went to the remaining woman. When she saw me approaching she said:"he will be with you soon". I went to "him", and "he" left without a word. Very reluctantly, the lady checked me in after a while. the keys did not open the door. The elevators took for ever to arrive. Sometimes one has to wait 10-15 minutes until you get one to stop. The food in the Ibiza (the hotel's restaurant) is edible, but not more than edible. They also tried to charge me 3 days of internet for 2 days stay. 
In short: STAY AWAY FROM IT
