clare1985- I'm at Rosebery lol. The rents here start at £70 (Basement room
) and go up to around £115ish depending on your room type.
The hall itself is pretty good, very good location to live in London (you'll realise it if/when you visit- here has a proper sainsburies by it etc), good atmosphere, cheap bar etc.
BTW- Carr Saunders isn't anywhere near as good as here. Also, have you looked into the cost of accommodation in your 2nd/3rd years? You won't get much for below £4000 a year.
