Our stay was very nice. The staff was great. The only issue was that the shower leaked out to the bathroom floor and then to the entryway because the door for the shower was not secured to prevent leaks when closed. That didn’t deter the nice time we had.

I stay here about twice a year for various reasons. Overall, the room was pretty clean, the staff was friendly and breakfast was good. The trash can in the bedrom area didn’t have a trash bag, so the desk attendant gave me a laundry bag. The grout in the shower needed tending to. Additionally, they ran out of wings at the bar, so I had to leave the hotel to get food. I would still recommend staying here; no place is perfect. They also give you a warm cookie at check in, which I love.
