A global housing listings website, completely free, in which the offers are shown on Google Maps in order to make the ones that are relevant for you easier to find. It also integrates RapLeaf, an open and portable reputation system, to help you find out about your potential flatmates/tenants/landlords, and to build and spread your reputation (and because it's "portable", your RapLeaf's reputation can be used anywhere you go, not only in vivirama).
