Although I booked a room with two beds online at www.hilton.com I wasn't given one. The clerk said all of their rooms only have one bed. She blamed the Internet for "sometimes getting it wrong."
It was noisy as there were people running up and down the hall all night. So I doubt there is any night time security.
Shower head was screwed in and couldn't be adjusted. It was set at five feet. I won't stay here again nor will I book via Hilton.com.
