What is a hostel?

What is a hostel?
Some information from Wikipedia...
"Hostels provide budget-oriented, sociable accommodation where guests can rent a bed, usually a bunk bed, in a dormitory and share a bathroom, lounge and sometimes a kitchen. Rooms can be mixed or single-sex, although private rooms may also be available."...

Differences from hotels
..."There are several differences between hostels and hotels, including:

1. Hostels tend to be budget-oriented; rates are considerably lower, and many hostels have programs to share books, DVDs and other items.
   
2. For those who prefer an informal environment, hostels do not usually have the same level of formality as hotels.
   
3. For those who prefer to socialize with their fellow guests, hostels usually have more common areas and opportunities to socialize. The dormitory aspect of hostels also increases the social factor.
   
4. Hostels are generally self-catering"...

Communal accommodation
..."There is less privacy in a hostel than in a hotel. Sharing sleeping accommodation in a hostel is very different from staying in a private room in a hotel or bed and breakfast, and might not be comfortable for those requiring more privacy. Hostels encourage more social interaction between guests due to the shared sleeping areas and communal areas such as lounges, kitchens and internet cafes." ...
