As far as water and facilities are concerned I would say it is a great place to be. I visit it weekly and I have a lot of fun. The pool is almost always quite free of people and you can swim (or try to not drown) freely.

Well maybe they just don't like me.
Anyhow the lifeguards are a breath of fresh air, always smiling and ready to help. They even let me borrow a pair of goggles when mine broke so cheers to them. read more
