Location was great. Room was clean but it was just a basic room no frills. Breakfast was a disappointment. The woman when we checked out was to busy on the phone with personal stuff to help us and after awhile someone else checked us out. Not sure if we'll stay here again.

Pool staff were nice. Suggest that check in let people know to bring an ID to the pool if they’d like to get alcoholic drinks. Pool area structures are rusty and look dilapidated.
