Buenos Aires [1] has abundant accommodations in all categories. Since 2002’s economic implosion, some opportunistic hoteliers have established higher rates for foreigners; if they insist on this, there’s little you can do except go elsewhere or, if your language skills are good enough, try to argue the point. Advertised rates at top-end hotels often exclude the 21 percent IVA, but prices listed in this travel guide do include taxes.
