We visit Chile frequently, and usually stay at the Orly, preferring the main building, not the annex. Our last visit was during Chile's violent disturbances and the hotel staff was simply outstanding! They found us open restaurants, kept the laundry and all facilities operating, and even sat up all night guarding the doors.]
It is well located, reasonably priced, and staffed by very helpful and attentive staff. It only offers breakfast, but the area is surrounded with an abundance of great restaurants.
