This is our go to place when we're in the area. Rooms are spacious and not congested like other hotels. The smell of the wood burning oven from the restaurant downstairs is very appealing. That my option because i like the smell of buring wood. The front desk staff are always friendly and accommodating.

Room wasn’t the cleanest. Stayed here 3 or 4 times prior to this so we expected better. Had to wash the glasses before drinking out of them as they were beyond spotty. Not sure how someone missed that. Otherwise a good stay as always.
