Portola valley training center (PVTC) vintage lane barn

Has anyone tried this barn out? I’m looking for a barn that is not too expensive, for lesson and leasing opportunity in portola valley.
I really like the facility of the training center, but most barns there charges $100/lesson, it’s pretty crazy. This is the only barn that charges $70, much more reasonable.
In general, how does leasing with a lesson at work? I’m just trying to estimate how much it will cost per month. A lot of half leases he are around 2-300 in portola valley, much cheaper if I go south or east bay,but I really don’t want to be too far out.

I just don’t know how it works to lease a lesson horse plus a weekly lesson will cost?

Anyone in the area leased lesson horse before? How does that work?
