Go and have a look on www.homeexchange.com
If you're on a budget, you can exchange your own place with someone else. Might be worth opening a profile and see who's interested. You would only have to take care of the flight.
I'm doing the same thing for Brazil and swap my place with someone there, to avoid paying rent for expensive holiday apartments. Go give it a shot I'd say:-)
I would suggest paying 10 euro a month as a member of the website. But that's not expensive at all if it allows you to travel all around the world and swap your place with anyone who's interested. Good luck!
