I'm a French gay man living in London for 8 years now. I've been hosting for over two years – I love meeting people from all over the world.
Addicted to London, I try to enjoy it as much as possible, visiting galleries, exhibitions, museums, trying restaurants and bars, going to gigs (indie/electro/pop, rock) and exploring the alternative art scenes. I occasionally give street art tours (part of my membership of (website hidden) - ask me if you are interested) .
Also addicted to music, I can recommend a good list of record shops.
I will provide you with a list of bars/restaurants/supermarkets in the area... and will help you to organise your stay as much as possible.
