For the price, I expected a more clean and updated property. Our first room had towel bars pulled off the walls with exposed holes in the bathroom, along with broken shower head attachment . Previous customer had also stuck a Kleenex in one of the vents that was still there. The staff did accommodate us changing rooms. The second room was much better, but had a used bath towel still in bathroom. Shows lack of attention and thoroughness of cleaning. Overall the carpet, doors, trim were all in poor condition throughout building. The location was the best thing about it, but overpriced for lack of quality.

Top notch staff, superb food, Great bartenders, bathroom and room extremely clean. Only thing to advise other travelers about is prices in restaurants. Food is outstanding but is not cheap, you get what you pay.for.
