Travelocity Verified Review
"The Pennywell was just fine as far as hotels go, pretty much what you would expect from a Hilton property. The bar closes at 11:00pm, which was odd, also. The fan on the HVAC system is always on when the system is on, the "auto" setting did not turn it off when the set temperature was achieved, which was a little annoying."
