Questions 168-171 refer to the following article. Business travelers find that some jobs take them away from home for longer than a few days at a time. Those who find themselves at a new job site for weeks or even months often find it more comfortable and economical to stay at an apartment-hotel rather than a traditional style hotel. The comfort and convenience of these short-term residences are making them more and more popular among frequent business travelers. They provide advantages that moreluxurious traditional hotels do not. Apartment-hotels offer both small and full-size apartments that are available to rent on a weekly or monthly basis. Apartments are fully furnished with everything from sofas and writing desks to dishes and silverware. They also usually include cable TV service and Internet access. Best of all, they are run like hotels, with cleaning and linen services, exercise rooms and restaurants, and a desk clerk to take messages and help tenants with questions about the city. In addition, the prices are much more reasonable than the rates normally charged at a traditional hotel. One of the reasons that many apartment-hotels are economically priced is that they are often not found in a city’s downtown area. This is not necessarily a disadvantage, however. They are usually conveniently located near public transportation, so the expense of a rental car is not always necessary. In short, apartment-hotels offer a convenient alternative to the business traveler, as they are more cost-effective than traditional hotels and more comfortable than hastily furnished apartments. Many business travelers find that apartment-hotels are as comfortable as it is possible to be away from home. Why are these residences called "apartment-hotels"
