Quick overview of Airbnb - It is a trusted community marketplace for people to list, discover, and book unique accommodations from around the world. Forget hotels. This service enables you to find apartments, houses, even castles if you like. They have properties registered in over 19,000 cities and in 192 countries and it's growing rapidly. Once you stay at a place, Airbnb calls them "hosts", you can review the host on the website or on the mobile apps they provide.
The design of their site is great and they haven't let us down in the apps either. Both the iOS and Android apps are amazingly designed and are real easy to use. You can find out information on hosts right within the app, info such as price, pictures of the place and where it is. You can search for nearby hosts with the GPS in your phone. They also have a features section, displaying the best places to stay and some funny ones - such as accommodations which are based in planes, trains or automobiles.
If you travel a lot or are caught short and need somewhere to stay, this app is a must have.
