    When we arrived around 5:30, the front office was already closed and we were lucky to run into and employee who took us to our room. The room was very run down, but clean enough. No bed bugs. There were a lot of flies however, which I thought was odd. Traditional style lock and key and in a super cute part of town. It’s right down the street from base so that’s really nice. Overall it was ok.

    Tv didn't work, no ice, very noisy , no lighting near bed, bed noisy, 2 flights of stairs to get to room which were noisy, light thru door.

    This motel appears to also be home to low income housing. I feared for my safety so I DID NOT end up spending the night. There was an overwhelming odor of bleach upon entering the room. There was no safety chain or dead bolt. Blinds were broken in such a way to give straight line view to the bed. That person on the 2nd floor watched me in my car for 30 minutes

    Parking is convenient and safe. the room was clean and the shower worked well. I didn't find any utensils in the kitchen, but I didn't need any. The refigerator was running but the stuff I put in there wasn't cold in the morning. In fact it was barely cool. But I slept well.

    The hot water took a little while to heat up in the bathroom, but that is a minor issue.

  • Engine customer Jan 2026

    The view, although the dock was not kept. The staff and view were perfect! The property was run down and dirty, dirty. Arrived at close to 5:30. Nothing was ready and there original room was not what we paid for. They were going to add a bed to a single room. No Internet or TV the bill wasn’t paid.

    The location was perfect , I just wanted the view of the water and the calm . Perfect ?

  • Engine customer Jan 2026

    Terrible This place is a complete dump. Very disgusting. Black mold in the bathroom, major water damage, rodent droppings under the bathroom sink, filthy mattress. Completely overpriced for what is provided. Should not be allowed to be in operation. Booked 5 nights, left after 1 and demanded full refund.

  • Engine customer Jan 2026

    The view and the community the local people are very friendly. Due to my personal situation out of state. I was asked to leave by Wayne. The message was given to me by Sam. Which would not have affected me or anyone else at the Inn. I will never return due to how I was treated so poorly during my time of need.

  • Engine customer Jan 2026

    The staff was very professional, Courteous,and Accommodating. Wayne & Sam were on their top level of the Hotel game. Nothing comes to mind at this time. Other than the weather just wouldn't act right.

    The location was great and the view over the river was wonderful. Staff was friendly, the room was clean and spacious, and the value was excellent. The hot water took a little while to heat up in the bathroom, but that is a minor issue.
