Noisy air conditioner.
Saw an inexplicable charge in my checking account that I assumed was an inflated restaurant bill added to charge (your restaurant's charge machine wasn't working, so it was added to the room bill). Called desk at about 11:30 PM, was told that only day manager could fix if there was an error. I asked her simply to check my account to see whether the charge you have was accurate. Was put on hold, and after ten minutes waiting I hung up. She never called back. Had she checked my account, she'd have confirmed that the correct amount had indeed been added to my bill and my concerns were unjustified. In fact, when I again checked my bank account the next morning, I learned that the disputed figure was a charge from another establishment, not yours. It would have been nice to know that the previous night.
One more thing: Your rear parking lot was filled with goose excrement and an open trash bin. Not very attractive, especially when seen from one's window. If you have a goose problem because of your proximity to the river, someone ought to be cleaning that area regularly.
Good bed, nice amenities in room. Daytime front desk staff pleasant and accommodating. Buffet breakfast good, restaurant meal quite good, friendly restaurant staff.
