We stayed at MainStay Suites Denver Tech Center from summer 2026. From night one we faced a severe German cockroach infestation. We regularly killed 40–50 cockroaches a day. They were in the cabinets, silverware, walls, ceilings, bathroom, toilet paper, tissue boxes, and next to our faces in bed. We also saw live and dead rats near the dumpster and parking lot. When moved to a second room it was still heavily infested and reeked of dog urine (visible carpet stains). The smell made my pregnant wife repeatedly ill. Staff and management were told about her pregnancy and the health risks from the beginning. We reported the problem to the front desk over 10 times. Every time we were promised traps, maintenance, or an exterminator. Nothing was ever done. We escalated to Choice Hotels corporate, requested relocation to a clean sister property, and later asked for a refund. The only offer was a two-night credit at the same hotel. They refused to refund anything. We filed formal complaints with associated departments. We also appeared on Tom Martino’s Troubleshooter. Despite all of this, no refund was provided. No one should live with cockroaches in their food, bedding, and personal items for months while being told “pest control is coming.” The conditions were a clear health failure, especially for a pregnant guest. We never got a single decent night of sleep.

The staff were friendly, professional, and helpful throughout our stay, especially during check-in and when we reported the issues we encountered. Unfortunately, the property itself had a serious pest problem. The first room we were assigned had numerous cockroaches crawling on the floors and walls, becoming even more active when the lights were turned on. We immediately notified the front desk, and they apologized and moved us to another room. Sadly, the second room had the same issue. We also found evidence of bed bugs, making us uncomfortable staying at the property. After notifying the staff again, they were understanding, apologized, and processed a full refund without issue. While I appreciate how courteously the staff handled the situation, the condition of the rooms made the hotel uninhabitable for us, and we chose to stay elsewhere.

Cockroaches. Bathroom door kicked in - wouldn't close. Sign posted at front door from City of Centennial Building Division stating Habitable Repairs Required limiting access to 1st floor rooms only?! Concerning but not surprising considering condition of Property. Really bad. Do not book at this Hotel.

Te atienden con rabia no son serviciales .

We booked two nights but left first thing in the morning after the first night. This place is terrible. The immediate issue is the smell when you walk in the door. Boxes are piled up behind the front desk. The doors in the bathroom and in the closet couldn't close because they weren't square. This hotel is a complete mess. All the fire doors in the stairway are blocked open, and there are machinery sounds all throughout the building. This was an absolutely hideous experience. Never again.

The place was infested with bugs and the front desk didnt care or do anything about it. I called corporate asking for help with the situation and even the supervisor Nalla said she cant help you have to deal with the front desk. I emailed the VP and sent photos of the infestation and never recieved a reply. Choice hotel chain is horrible and I will never stay at another one of their properties again.

The room had roaches. I requested a new room and it also had numerous roaches on the counters and floor. We checked out immediately. Staff acted like they were not aware. Which is horrible. With that many issues they should be aware.

“The room was dirty on arrival and the bathtub was clogged basic upkeep that shouldn’t have been missed. Even more concerning: this is supposedly a non-smoking hotel, but the smell of smoke hits you throughout the entire building. Either housekeeping isn’t checking rooms between guests, or the no-smoking policy isn’t enforced at all. Would not recommend

Checking in I found out the elevator not working. Not good when I have to use a cane. Climbing one flight of stairs was okay. The room smelled of cigarette smoke and musty curtains. Everything else good.

Cockroaches. It was awful. We left early and asked for a refund for the second night. We were not the only ones leaving because of infestation.
