This the big question.
The good side: location (two spots in midtown! the 54th Street studios are FANTASTIC. the 8th Avenue studios just pass muster, but some of them are great just due to SIZE). Prices are decent.
The bad side: frequent mis-scheduling/double booking, poor communication with renters, difficulty in dealing with the staff is an almost daily problem.
But in the end, sometimes you just schedule here because you need to (due to space size, time or location). Book late and they give a big fat discount. Just hope that your booking was the only one for that time/space. Or make friends with an employee.
