Historically, the usual appearance of a Residence Inn was a main building, called the "Gatehouse," which houses the front desk, a common area for meal service, an on-site coin operated laundry, a swimming pool and exercise room and often several out-buildings similar to condo or apartment complexes. Most had interior corridors. More recent constructions, however, have moved away from the out-building style and instead have a more traditional layout with all suites in the same building. The suites are much larger than traditional hotel rooms, however. They are typically around 450 square feet for a standard suite and 650 for a two-bedroom suite. Residence Inns typically feature a complimentary small hot breakfast in the morning and a free light dinner or snack reception on weekday evenings, Monday through Wednesday or Thursday. - Source: Wikipedia
