Airbnb is a website that allows anyone to rent out a bed to paying guests and allows travellers to search for available accommodation. Anyone can post a bed on the site and anyone can take them up on the offer. The listings include vacation rentals, private rooms, entire apartments, bed and breakfasts and many other traditional and non-traditional accommodation.
The listed beds/rooms include user reviews, photographs, a description of the accommodation on offer and a Google Map showing its location.
Google Maps is also used to show the locations of accommodation when you carry out a search. So, for example, if you search for accommodation in San Francisco for a particular week the places that have rooms available are shown on a handy Google Map.
