I've lived 'around' LJ for 5 years now and I love living here.
I'm bringing up my two kids here. It's really friendly - I know more than half the people on my street, something that's never happened before in London, and they're all really nice.
Ruskin Park is small but a very nice green space, and is being done up at the moment (public lavatories, bandstand, changing rooms for sports etc). Great playground and paddling pool for kids, always full of friends to play with. Tennis courts, football pitches, a cricket wicket, duck pond, ornamental gardens, 'wilderness' areas, a nature walk.
It's less than a mile to Brixton Tube (just, but it is), plus 4 buses run there if you're really lazy.
And LJ Thameslink is not perfect by any means but will get you into town in 20 minutes, or further afield if you want... (except on Sunday afternoons...). And it's got a cafe where you can get a cuppa while you wait.
The 35 and 345 buses run 24 hour, so you can get home from most parts of town that way too if you need.
The newish 'Kashmir Halal' shop does decent quality/price vegetables (and meat too if you're not fussy), and is open late too; there are any number of 'convenience' stores, some even quite well stocked. Yeahman Garage has always done good cheap work for me. Phillips (on Loughborough Road) is a damn fine butcher. The Cambria is an decent pub. Zest of India do a good value Biryani. The Red Gate Gallery does fun things occasionally (although I might be a bit out of date now?).
Yes it's a bit run down, yes 'regeneration' is proceeding slowly if at all, yes the Harriers has been a (disgraceful) hole in the ground for nearly 2 years now, yes pubs are in short supply,yes there are still several boarded up shop fronts which is a waste; but there is new social housing being built behind the petrol station on Hinton Road, the Green Man and Warrior *are* being re-developed, the Warrior as a pub which will be excellent, there are plans for more housing behind the Warrior, all of which should bring more people and therefore hopefully businesses into the area.
Up the Junction!
