In terms of schools stillness, dalmain and fairlawn are really good primary schools. You cannot go wrong with either hop or fh both offer slightly different things but easily commutable to each other and east dulwich.

We chose hop over east dulwich mainly due to cost but transport and schools played a part in the decision where we felt hop won over fh particularly on schooling and with crofton park a 15-20min walk away you have direct trains to blackfrairs, farringdon, kings cross etc.
