I am also at Stapleford, on my CPL, although I am doing the modular route so did my PPL and ATPLs at other schools.
So far I have completed my hours building and half of my CPL there.
The school appears well run and my instructor is very very good. Because I am still working they bent over backwards to get me flying and sim slots to fit.
I live 90 miles away and drive in almost daily so it can't be that bad to hold me there.
But its and big step this ATPL lark so it does make sense to visit a few schools before you make your decision.
Good luck wherever you choose.
