For housing = yes it is crazy.

For loads of clubs - you'll pay the same. There are hundreds of tiny clubs in London - many offering free or very cheap entry every night of the week. Yes London has a few expensive clubs (that are generally rubbish once you are in if you aren't paying for champagne) - it has loads of great places to see live music, comedy, djs and acts for pocket money. Just pick up a copy and Time Out and you'll def find soemthing you are interested in... 'If one is bored of London...'
