I do not see a master thread for this hotel so I decided to start one. I had a one night stay at this Hotel. Very nice hotel my top property for SPG in Denver (I am local).

This hotel Is unbranded property--not Tributes or any brand

cons

Parking--$38 valet per night. Self parking $20 with no in and out allowed
no robes in room or slippers. You can ask and they will bring you robes but slippers are not available
Coffee cup in room are very cheap (thin paper cups without lids or sleeves)

Pro

Excellent Platinum Breakfast--any entry on the breakfast menu plus one drink served in Harry Bar
room upgrade used a SNA upgraded further to a suite with a fireplace
Harry Bar--very nice place to get a drink or snack
Complimentary car service in the downtown Denver Central Business District (7 am to 11 pm) need to talk to valet person -- In the future I will use this to pick me up at union station.
