"This is my 4th trip to the Biltmore. I have always enjoyed this property and had a wonderful time but this trip was different. The Catalina pool was closed for maintenance on my 3rd day at the resort and other pools including the Ocitilla pool were in need of cleaning. The pool tile was being cleaned while swimmers were in the pool and there was a bad film of sunblock on top of the pool indicating the filtration system was not working properly. The adjacent hot tub water was so dirty, I would not get in it. Overall, the pool maintenance was lacking. It was so disappointing and when we notified the staff on check-out the front desk staff was indifferent and not apologetic. It was disappointing to say the least. Hopefully, things will improve."
