Hi everyone! I'm in London now and I would like to practice
my english... Anybody knows someplaces or where I can
have a language exchange?
Pub.
Practies it everywhere you go to. When you go for example to the resturant, ask the waiter to get your order and try to talk with him/her about anything for a while. Then, let him/her to go to see other customer.
Enjoy
Speak to some locals ;)
Look on meetup.com for some groups to go along to there are many in London. Also look omn the gumtree website there are also ones advertised there.
