Yeah I definatley reccomend you check out hospitality club, reakon it could help save a lot of cash!!!!Ive also mominated myself to allow randoms to crash on my floor and show them around but i guess i would have to be pretty sure on the person before i let them into my house!Been in contact with a really cool girl from Germany who is studying at the Bunka Fashion school over there which is perfect as im also a fashion student so maybe hospitality club will turn out great!will be sure to let you all know how it goes!!!!
Another great site is the CouchSurfing Project --- http://couchsurfing.com/
I'm registered and it's great you can view and post pics of other people's couches or your own. They have a vouching/friends system where other members can give feedback on how their experience with that person was through hosting or as a guest.
Thanks for all your comments. I registered with freeloaders a couple of weeks ago and had a request from someone i wasnt sure about .. think ill check out the hospitality club, see what i can find ...
