We moved from Grafton Road which is probably at the top if Poets Corner (although to be honest that is just EA speak) and the houses there, on the edge were selling at about £1.35mill. I echo the sentiment that Perryn Rd etc is slightly cheaper and still lovely, very close to the park (which is one of the best things about Acton, the park is fantastic with the most lovely little cafe at its centre). Churchfield Rd is really great now with a couple of fab pubs, cafes, delis, a GREAT barbers, and a brill indie wine shop that have wine tastings regularly. There are development plans afoot at the top of Churchfield Rd, where a big multi-million pound development is going up and i think a lot of stores are proposed for there. Not on Churchfield Rd but just up the road is The Aeronaut which is my top recommendation for the area, definitely seek it out! Acton centre needs a bit of a facelift admittedly but it has a multicultural vibe and you can find pretty much anything you need on a day to day basis. Our daughter thrived at the Montessori Nursery, and as others have said, there is a very nice little school there. With Crossrail coming, Acton is ripe for development and although i think you are buying there a bit after the boom in prices (our flat went from £385k to 550k in 2 years!) there is still investment to be had.
Ealing Broadway/common are walkable and Chiswick High Rd is only about 12 mins on the bus away. I TOTALLY disagree with the pp who said Acton has so little going on, they clearly have not lived there - or certainly not recently.
As it happens, prior to moving to Acton we lived in Pitshanger as well and it is my favourite place in London. Very villagey feel, lovely cottages, conservation area, great 'high street' on the Lane and there are so many events organised throughout the year that really appeal to families. Great pub, restaurants and cafes with a lovely little bookshop and a beautiful park. We got married in St Barnabas on the Lane! Lovely GP. I could rave about it all day. No tube, only buses to Ealing Broadway but they are very regular and we had no problems living there without a car. 4 beds are still coming in under £1 million.
This is making me yearn for my old stomping grounds now!
Good luck on your search OP
