8/10 Very Good! (10,286 reviews)
"The hotel appears to be nice but it is not. The paint is peeling off the walls/ceiling. The A/C in the room had a knob that made a 360 degree turn from heat to cold and you couldn’t tell if it was working. A/C not properly working. Overall, it seemed run down and really needs an upgrade."
