Parking time is generous at 3 hours. I remember it being 1 hour before, but I'm not sure if it's been extended.
The waiting time is a bit longer than that of other hospitals, but there are so many hospitals with long waiting times these days that it would be better to take that into consideration when you have time.
The staff and doctors are generally friendly~~ The waiting chairs are a bit uncomfortable and you have to wait on the sofa while getting anesthetic cream applied, but the price covers it. I've been getting laser treatments here for a long time, and although the doctors change every time, I remember being overall satisfied, so it's a good place to get light treatments!
