Don't underestimate Queen's College. It's a much improved school which the Good Schools' Guide says is "one to watch". It has a lovely, focused Head Master who wants the school to do well by its girls. Buzzy atmosphere. Polite girls. Some really clever ones there too.
Attracts girls from all over London because of its Central London location but Francis Holland is right opposite Regent's Park which is better for those north of the river.
Does anyone have a daughter at Queen's now?
