I work here and tbh I wouldn't live here.
It's a little bit run down, but not terribly.
Mix of people - ??? I'd say it was mainly asian.
No idea about the schools, sorry.
Things to do with kids - err well there's a few parks,a wacky warehouse and bunny park in Hanwell isn't far away.
Safe - well, i don't feel scared on a day to day basis, however tbh NO, not it isn't safe, there has been a few murders, muggings, assults. Horseendon Hill has had a few bodies discovered on it, there was a sign asking for witnesses to a serious sexual assult there the other day. A few years ago a school boy was stabbed on Bilton Rd.
On Bilton Rd, the little local shops, there is often 1 or 2 drunks on the bench.
However this is all centered round Horsendon Hill and then Bilton Road.
There are other parts to Greenford and to Perivale and I can't talk about them, I'm sure they are all fine.
Have you looked at South Ruislip, not a million miles from Greenford and may be the same price range, and that has nice schools ands I would say is a nicer area.
Or maybe look at Eastcote, Ruislip Manor, Rayners lane, South Harrow?
I'll come back later to see if you have any questions.
