Check out my new discovery: FlatNav a new, safe, online marketplace and social network for people to list and find short-term accommodation and vacation rentals. What I like about it most is the fact that if you go on holiday alone, you won't have to worry about being in a strange place by yourself. You can find a friendly host. Hosts can list their spaces for free, anywhere in the world and travellers connect with them to stay at their amazing homes. Moreover it's eco-travel. Check out the video which explains more.
