The siskey Y is convenient  for me. I commute to Monroe from Charlotte during the week and stop by this location in Matthews on the way home.  The employees are great and I've never had an issue with cleanliness. It's a little too crowded for my taste, though. I've had to wait for a machine several times during peek hours. They don't do a great job of monitoring their machines during rush hour. Some people use them for 60 + minutes when the machines have a 30 minute limit, which is very frustrating.
