Incompetent, unclean, and boring
Had problems checking in and out, and in between. But first, don’t believe the hype on this hotel’s website. This hotel is near nothing. The restaurants and clubs listed as “nearby” are elsewhere in Denver, but you will need transportation. It’s a long walk to the train, despite the claim for it being near. Long walk to a busy intersection, then under a set of interstate bridges. There were homeless people under the bridges asking for a handout. 
Check in was a miserable experience with an incompetent clerk that could not understand a simple question regarding a company credit card. Three times she left and came back with answers that were irrelevant junk. Finally talked to some chubby manager that was equally clueless—didn’t even bother to check, just said “no” when he finally grasped my question. I had to use a personal card, and then was punished with the noisiest room with a view of the front parking lot—the clerk even bragged to my face that she was sticking me in that room for making her “look bad” in front of the manager. 
Tried twice over the next three days to resolve the CC issue, each time met with indifference and incompetence at the front desk. Another thirty minutes to check out and still wound up with spurious charges on my personal card. Seriously, this hotel is staffed by untrained workers that are indifferent and clueless.
The entire place is filthy. The hallway carpet was covered with the same debris (leaves, threads, glitter, paper and other detritus) the entire four days I was there. A cigarillo butt was in one hall corner the entire time. Hard to miss, but who knows how long it’s sat there. A partially eaten box lunch sat next to the trash can near the elevator for an entire day and evening. Which explains the bugs. Ceilings in the hall and in the bathroom were cheap hanging industrial acoustical tiles, many were stained. I’ve never been in a Motel 6, but I’m betting this is the way they look inside. I had bugs in the bathroom, not surprising with a filthy hall and loose ceiling tiles. They never cleaned the in-room coffee service all the time I was there, and only provide decaf unless you beg (three mornings, then I gave up; had to ask for condiments and shampoo as well). Room walls so thin you could hear every conversation in adjacent rooms. I did visit a guest room on the west side that had mountain views-- across multiple lanes of interstate traffic. We could barely hear ourselves without raising our voices over the roar of the traffic. So much for scenery. 
There was a refrigerator in the room. No place in walking distance to buy anything. Believe it or not, in this “classy” place one of the cabinet doors for the ‘fridge and fallen off and they never bothered repairing it, just left it partially open with half its doors. The mini ‘fridge had an ice ball around the freezer compartment-- hadn’t been cleaned or defrosted in months. It wasn’t cold inside and it buzzed and groaned constantly. Yet they list this piece of junk as an “amenity” in the hotel room description—what a farce. 
Finally, (not really done with all that I dislike about this place, but I’ve spent enough time on this hole) the restaurant (glorified snack bar) and in-room dining are mediocre and way overpriced. This hotel is one of the worse deals, ever. Avoid.
