The airport is big but very quiet. This is probably the friendliest school I know with a great fleet of aircraft and brilliant instructors. The owners of the school are extremely proactive and both actively participate in GA flying. Every Saturday they serve loads of (free) pizza on the patio where you can just sit back, scoff pizza and watch the weather or the odd aircraft doing circuits.
Can't recommend it highly enough.
