Elstree is great, I have worked there onvand off since 2007 and it has changed for the better in many ways.
There are quite a few schools so it's worth doing your homework, picking a school at Elstree depends on the type of experience you want from it, IE the club feel, fly outs etc or just rock up, hire and fly. There's also a new Taxiway to the runway now, so 3 in total making life easier and quicker for all.
Pop down, walk about and grab some food in the restaurant.
