"A hotel is an establishment that provides lodging paid on a short-term basis. The provision of basic accommodation, in times past, consisting only of a room with a bed, a cupboard, a small table and a washstand has largely been replaced by rooms with modern facilities, including en-suite bathrooms and air conditioning or climate control. Additional common features found in hotel rooms are a telephone, an alarm clock, a television, a safe, a mini-bar with snack foods and drinks, and facilities for making tea and coffee.
