San Diego Surfing Academy

I've just booked a couple lessons at San Diego Surfing Academy for my holiday in San Diego in 2 weeks time after viewing their web site.
I then read a really bad review that I found online. It may just be the usual one off but I am hoping that someone here has experience with or knowledge of them that will reassure me.
