- It was good
- Rating: ⭐⭐⭐⭐☆ (4/5)"Had a great stay at the Days Inn Thornton! The room was solid—very comfortable bed and a nice hot shower. The check-in process was fast and easy, which I really appreciated. They offer a breakfast that is fairly basic, but it definitely gets the job done before you head out. Plus, there’s a convenience store within walking distance. Overall, a 4/5 experience for the value!"
- Breakfast was included
Cons -
- I asked for more towels and extra coffee for the room and was told they can't access the housekeeping supplies. Which is a lie because I worked at hotels before. There is always access to housekeeping if you are booking rooms.
- Zero complaints. 4/5 stay! ⭐
- Our hallway smelled like marijuana the entire time, despite being non-smoking, our room window had been force open at some point and was gapped open 1” to the open air outside, our shower stall had a large crack running through the base, the parking lot had broken down/inoperable cars taking up parking space, the pool was closed the entire stay. The staff ignored us for ten minutes upon checkin, while we watched them microwave their dinner.
