In no particular order:-
Cafes and restaurants and cosy pubs
Buzzy high street with some independent and useful shops
Playground, Football pitch, decent Clubs for kids and things for them to do when they are teens
Large park nearby or access to pretty countryside
Parkrun and good running routes
Easy commute to Cannon Street/city - 45 mins would be good but would look at 1hr
Not too busy
Friendly community feel
Gym and pool
Nurturing primary school - middle ground between academic and chilled. Two form entry preferred
Good state mixed secondary school - walkable
Option of good private back up
