Just as the title says, for each value, £100/£150/£300 a week, where would you live?
For £100 a week, I'd probably try to share a room in somewhere like camden as basically that seems to be all it gets you
for £150 a week, I'd probably try to get a rubbishy single room, close in, like hopefully somewhere baker st-ish
for £250 a week, i'd be torn between a wee flat in a townhouse maida vale-ish, or trying to get a studio in W1
