Lodging or a holiday accommodation is a type of residential accommodation. People who travel and stay away from house for more than a day need lodging for sleep, rest, food, safety, shelter from cold temperatures or rain, storage of luggage and access to common household functions.[1]
A hostel is a building that is used to provide accommodation facilities to visitors. Hostels contain many rooms that contain several beds to provide sleeping facilities to several people. Generally hostels have common bathrooms in a floor, and some hostels also have kitchen facilities to provide food to the inmates.
