The breakfast had very lean offerings and was very disappointing. Seriously, on a two week trip with 8 motel stays, it was the leanest and lamest. Oddly, the rooms had 1. No cups to drink from 2. No coffee machine 3. No pen or paper 4. No guide for the motel (i.e. info packet) 5. No USB plug in places (would need adaptor for wall), broken curtain pull. The hotel had just switched overhead from something else to Marriott and maybe that played into things, but Marriott needs to step up their game for this one. Plus sides: the airport shuttle, the staff, and walking distance to various resteraunts and a gas station or two for things one may need when an unexpected overnight in Denver happens with no baggage . . .

The hotel has nice features, like the rooftop restaurant and bar, and plenty of space to relax and roam. The room was underwhelming. The intent of design is felt but poorly executed, like the cheap lounging chair, the weird wall-length desk blocking the window, the metal drain that pops up above the shower floor, and the window shade that was ripped to shreds because it doesn't actually fit properly in its guide rails.

The staff was great, very responsive! Our first room had a loud banging with the AC unit so we requested to move rooms. Second room had a very slow draining sink and when the hair dryer was used blew the fuse for the entire room. Also loud trash emptying from building next door starting at 5 am, emptied twice that same morning. Overall the place was clean and well decorated, staff helped where they could and was very nice to interact with. Just disappointed we got the two rooms that had problems.
