Great location in the middle of the town and close to Mount Rushmore and a good point to start exploring the surrounding attractions. Clean and large rooms, parking available on site. A special mention for the ladies at the front desk. We had a problem with the car rental and all of them were so kind and helpful. We will never forget such kindness and will recommend the structure to everyone. Thank you again.

“Loved it.”

Fantastic location for the Sturgis Motorcycle Rally. We couldn't believe how quiet it was, given the fact that it was the week of the rally. Gretchen the lady who checked us in, must have a bit of British blood in her, the banter was just fantastic, she made the parting of 1600 US dollars almost painless. The room had everything that you needed for a good night's kip. The hotel's location is just perfect, you can literally walk out of the front door, and you're on the main street, where there are lots of places to eat, and look at all the bikes parked up. I love Keystone as it's got bags of character, and it's right where all the attractions are. We were there for 11 nights and we couldn't fault it. When we left, I mentioned to Gretchen that we were heading to Sioux Falls, she advised us not to miss the falls at Sioux Falls, and we didn't. So Gretchen, if you're reading this, thanks for the recommendation, we loved it.
