I live in a detached house in East London. We are a vegan, queer, commie household, and would be happy to host anyone who is comfortable with that. We have a huge living room/kitchen area downstairs, which has a fairly comfortable sofa to sleep on, but if it's more than one of you coming, up to 4-5 mats can fit on the floor.
You can't bring non-vegetarian food into the house, but we are happy to cook & eat together with you.
I'm here most of the time (maybe off for a couple of weeks), so feel free to contact me whenever.
P.S.: We live just by Epping Forest (not the zone 6 bit of it, no worries), so if you fancy a walk in the woods, we are happy to show you around there. (There is a cute lake with lots of ducks. :) )
