What guests think
Reviews of Mountain Inn describe a very mixed experience, with some guests praising easy check-in, friendly staff, spacious rooms, and a convenient location, while others report poor cleanliness, significant maintenance issues, and inconsistent front-desk availability.
Several reviewers also say the advertised breakfast is unavailable or extremely limited (sometimes just cereal), and coffee may not be provided. Comments about the area include occasional noise and multiple concerns about safety in the parking lot or neighborhood at night. Expect basic lodgings with variable upkeep and service.

Rooms
Rooms feel dated with recurring maintenance issues (broken TV/controls, nonworking lights or AC, hot-water or flooding problems, and lingering smoke or musty smells), though some are spacious and beds are comfortable. Experiences vary widely between rooms.
