Why do I always go back to Enterprise, even though it's got the worst kit, most obnoxious wanna-be rock-a-billy kids working there and most of the rooms smell like a mortuary running low on lime.

Can anyone suggest a decent practice space in East London that doesn't cost a fortune, has kit that actually works and where there is a remote possibility of getting a practice mid-week without having to book a year in advance?

Thanks.
