The Service

Sure, a 5-star hotel is aesthetically outstanding but more importantly, the service is essentially flawless. First, the staff is extremely well spoken, polite, and clear. They are trained to avoid slang and fragmented phrases and they carry themselves almost at attention, without hands in their pockets or folded in front of their bodies. Next, the staff will address you by your surname, whenever possible, and, from check-in to departure, they are at your beck and call. Lastly, a 5-star experience always includes an escort to your room, unless you specifically decline.
