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.

We had the perfect stay thanks to the staff and services. Roger at check-in was delightful as well as helpful and we were soon in our 'room with a view' on the 8th floor. Valet parking was easy, always quick, and the personnel were very courteous. Cocktails in the Peaks Lounge is an experience not to be missed, as we enjoyed a Denver skyline view while sipping curated cocktails. Best of all were the facials we received from Madena and a massage from Julia at Spa Juniper in the hotel. Excellent stay. Can't wait to repeat the experience.
