Holiday Pad is a website which offers alternative holidays. It does this by letting people register their unusual holiday destination or house, or whatever. Our friends in Normandy have listed their Earthship to get some proper coverage.
So if you are bored of the same old thing and want to rent an Earthship (or a treehouse, or a red cube, or just something completely different) go find it here. To bad you can’t book via the website though.
