I'm an interested and open minded person, I hope, living more or less in the same flat with my boyfriend Juan. As both of us rented a flat, there's one to share.
He can answer your mails in German, Spanish and English, I could also give my best in French. As long as you don't want us to speak Twi or Chinese, it shall work!
We had a few very good experiences with airbnb and now also want to give it a try.
