Is this place for a 4 year old? Are there rides that a 4 y-o can ride?

Of course, I was there 2 weeks ago and my 3 year old son had a lot of fun, in some rides he could go alone.

Yes, definitely. Driving included.

A lot depends on the child's height. Check the ride height requirements. But for the most part yes there are several rides for young children.

Yes my 4 year old had a blast yesterday.
