The city has a range of options from plush high-end business-style hotels to boutique guesthouses and hostels. Some visitors choose to stay in the characterless northern suburbs, but that is really no more convenient to the airport or bus terminal than staying downtown, and you’ll be forced to take taxis wherever you go. If you do choose to stay there, be sure to base your decision on each accommodation’s merits.
Street noise can be an annoyance regardless of the category of hotel; bring earplugs if you're a light sleeper.
Several standard-issue, business-class hotel chains like Hilton, Sheraton and Howard Johnson are out near the Mall del Sol.
