"The property was meticulously clean. The staff was more than helpful if you needed something everyone was very kind. The only thing I object is the parking fee of $20 a day. I don’t see why we should pay $20 a day on their property when we’re staying there other than that, everything was fine. The buffet breakfast was really good. The food was hot and clean. The place was clean and my service dog was safe there if I had to leave them for a little while to do something, I wasn’t worried about it. I’m Social Security. It was very tight. I stayed there many times before I never had a problem."
