For $5 per toddler on a Saturday morning, I really can't complain. This place is a facility and shouldn't be judged on service (at least the way we saw it during open bounce - maybe parties are different?).
There was an attendant in the room with us the whole time, but it's very much on the parent to ensure the safety of your child. Unfortunately there are some parents who don't see a need to enforce the rules; and to expect a 17 year old attendant to police a 14 year old running the wrong way up a bounce house slide is a little ridiculous. Bottom line - it's good cheap fun for small kids as long as you have an eagle eye and don't mind doing a little good natured parenting to other kids who aren't being supervised all that vigilantly. If you don't have the personality to tell other people's kids to tone it down, you probably want to avoid going here; because there were a couple of older kids who had zero supervision from their parents (in the corner reading a book) who saw no problems with aggressive horseplay around the 2 - 5 year old set with no regard for their safety.
The inflatables were clean, there was some wear on them from lots of use; but nothing was unsafe or stinky - again that might have been because we were the first of the day to be in there.
