I've been going to this studio for over a year, got my wife into it shortly after joining. We both feel the instructors are knowledgeable and friendly.
Aerial yoga seems intimidating but I think is easier than earth yoga. Part of your weight is being managed by the silk, so you're more in control of the pressure you apply in each position.
I would also recommend the Yin and Restorative classes, since they're much slower and provide deeper stretches.
