Nearly all of the following hotels offer transportation to the Salt Lake City Airport. Those with the lowest-numbered addresses on West North Temple Street are closest to downtown; these hotels are about a mile from Temple Square and downtown, and are inexpensive options if you're looking for a centrally located place to stay.
Gateway Motel (819 W. North Temple St., 801/533-0603 or 877/388-8311, $40 and up) is a budget hotel on the road to the airport but still quite close to downtown. Moderately priced rooms are available at the Motel 6 Airport (1990 W. North Temple St., 801/364-1053, www.motel6.com [1], $51 and up), where there's a pool.
Of the many older motor-court motels along North Temple Street, perhaps the best maintained is the Overniter Motor Inn (1500 W. North Temple St., 801/533-8300 or 800/914-8301, $75 and up), with an outdoor pool and clean rooms.
Although it's on the road to the airport, the Econo Lodge (715 W. North Temple St., 801/363-0062 or 800/877/233-2666, www.econolodge.com [2], $79 and up) is also convenient to downtown, as it's just west of the I-15 overpass. The motel offers a courtesy car to downtown or the airport and has a pool and guest laundry.
The Quality Inn SLC Airport (1659 W. North Temple St., 801/533-9000, www.qualityinnslc.com [3], $79 and up) offers nicely furnished rooms, a restaurant and private club, and a pool and spa. Practically next door to the airport terminal is the Ramada Salt Lake City (5575 W. Amelia Earhart Dr., 801/537-7020 or 800/272-6232, www.ramada.com [4], $68 and up), with a pool and spa.

North Temple St., 801/364-5800 or 800/333-3333, www.radisson.com [5], $139 and up) is a very attractive, lodge-like building with nicely furnished rooms. Guests receive a complimentary continental breakfast and newspaper, and in the evenings there's a "manager's reception" with free beverages. Facilities include a pool, spa, and fitness room. Suites come with a loft bedroom area. There's quite a range in room prices, though package rates and promotions can bring them down dramatically.
At the Airport Hilton (5151 Wiley Post Way, 801/539-1515 or 800/999-3736, www1.hilton.com, $167 and up), rooms are very spacious and nicely furnished, and facilities include two pools, a putting green, a sports court, and an exercise room and spa. The hotel even has its own lake.
