Having just moved to N20, I could do with some personal recommendations as to the best....
1.doctors...urgent!
2.dentists...urgent!
3.nursery/primary schools(thinking ahead here a bit!
4.cheapest places to do groceries by public transport instead of doing an internet shop
5.the best library for toddlers
6. Any second hand furniture shops?

We are at the end of Russell Lane that meets Oakleigh Road, to give a better idea of whre I can get by bus!
I know I'm lazy, and will probably find this all out in time, but its so much quicker to pick mn brains!
