You can try my club - Plusone - (
www.plusone.org). Normally you do need to be a member ($30/month I believe) but I've heard of people getting membership for 1-2 months and then cancelling when they leave. There is definitley someone from England who comes here and does that from time to time.
I can inquire if you are interested.
There are also a number of other clubs and schools in the area
