SFCM campuses are basically two nice buildings located in the middle of music / performance district. You would be surrounded by performing arts, great food culture and trendy cafe / stores. The area isn’t “college-y” environment at all. There aren’t other college students you would interact there.
SFCM is a true conservatory with amazing guitar faculty (I can’t stop mentioning Julian Lage). Jazz students seem like a making a very good encouraging community. They sometimes perform at SFJAZZ Center.
