Stayed in a Catbird Suite with a lofted bed. Room was clean and bathroom was big with a good shower. Room was efficient but awkward. Have to be very careful walking around the bed because it is on moveable drawers. Sofa bed is very uncomfortable and not good for anyone other than a small child. Hotel overall is pretentious and lacking warmth or a welcoming feeling from the staff, especially the guy at the weird front desk/bar/restaurant. Request for anything extra - such as a request to have housekeeping make the sofa bed - was met with thinly veiled annoyance and declined. Valet charge is $52 but they seem to park the cars in the $5 lot across the street, so skip the valet who won’t help take luggage out of the car anyway. Rooftop bar, which was a major reason we chose the hotel, was closed for a private event on 4th of July and our disappointment was met with an uninterested shrug.

Centrally located in downtown Denver. About a 30-minute walk to Coors Field to watch the Rockies. Dining/breakfast menu is a little pricey. Overall a nice hotel that is quiet and comfortable.
