Rooms and amenities were much better than expected. The pics online do not do it justice. Staff were professional and beyond friendly. They were proud to share their knowledge and history of the property.

Great location and cool design with different floors representing different themes. Free coffee in the morning. Sam’s number three next-door, which is a great local restaurant, famous from the tv show Diners Drive ins and Dives.
