Fair 4.0
I liked driving up to the handicapped drop-off and taking in the view of Bolt Castle. I was very disappointed with the room. I mean, the entire place was open, but they put me right next to the office, which is code for the noisy ice machine and people talking like nobody is there. The toilet flushed spontaneously. And there was only one dollar-sized disc of soap... no shampoo. No lotion. Nothing. I could make coffee, but they didn’t have plastic spoons or anything. The mattress and pillows were exceptionally hard. The TV was tiny and grainy. I am pretty easy to please, but the Bonnie Castle was a bust.

Good 6.0
Poor given the price of the stay
The room was outdated and could have used a cleaning. Cobwebs in the windows. I asked for a room upgrade and got it however, i wasn't told that my new room had it's river view obstructed by the boats stored at the marina at the close of the season. It wasn't a horrible stay but, given the cost, was very disappointing.
