Yeah, I'm currently in Wandsworth, near Northcote, and find it's too far from everything, plus no tube. I also got a bit fed up of the whole Nappy Valley thing, and just seeing mums with young kids (sorry, I know it's a great place, I just don't feel it's right for us).
I am thinking more of the NW, or the West, I know zones 1&2 are more expensive, but Wandsworth isn't cheap either and we're willing to sacrifice space and maybe pay a bit more.
Fulham sounds fine, but for the price, I feel I can get something similar even more central. I also try to avoid the District line, as it's usually closed during weekends.
Areas we are considering:
St Johns Wood
Swiss Cottage
Chalk Farm
Mayda Vale
Kilburn
Edgware Road
Notting Hill
Shepherds Bush
Barons Court
South Kensington
Earls Court
Fulham
I am also curious about Muswell Hill and The Crouch End, since I have read in another post there are many good schools there.
