Overall likely to be the best hotel of a few weeks trip. Rooms are like large suites, with good king bed and separate desk and sitting area. Fast wifi. Good bathroom (though with the old-fashioned sink in a corner of the room). Nice small outdoors pool and jacuzzi, good self service laundry facility.
Great location. Arena light rail stop is 10 mins from airport, and 2 stops from the city centre; as it's in the free city centre zone you are really minutes away from the Temple Square or the excellent City Creek mall.
Only the free breakfast is a level lower, 3 stars at most. Limited choice in breads, no cheese/meat slices (except cream cheese), limited hot options and limiyed fruit/cereals. All only on disposable cups etc, plates and cutlery are good quality. Just a small detriment to an overall excellent place.

Very clean, room setup is awesome. Great place to stay if you need to be in downtown salt lake, close to the delta center, temple square and abravenal hall. Also we noticed that the room was very quiet and the beds were really comfortable.
