My kid has done multiple summer camps at that location, and had a great time. However, it's definitely not my first choice for a toddler/preschooler (unless you posted in the wrong forum).
It's kind of gritty, and there are a lot of teens just kind of hanging out. That's not a criticism - teens need safe places to hang out, and they feel at home if it feels a little "dangerous" without actually being dangerous.
