Being next to the train tracks, I was worried it would be noisy, but there's no crossing nearby and the low rumble of the freight trains was barely noticeable. The hotel and room was modern, clean, and well-kept. The staff were friendly and the distance to the convention center is easily walkable. The kitchen was well equipped with a large fridge, two-burner induction hot plate, pots, pans, plates and utensils as well as a dishwasher. Would happily stay here again.

I recently stayed at the Sheraton Ontario Airport Hotel and had a wonderful experience. The hotel's location is incredibly convenient, being near the freeway and close to all the main areas, including shopping centers and the airport. This made arrivals and departures a breeze. The picturesque views from the hotel were quite relaxing and calming, adding a touch of serenity to my stay. The hotel itself was clean and well-maintained, with comfortable rooms and friendly staff who were always ready to assist. Overall, I highly recommend the Sheraton Ontario Airport Hotel for its convenience, beautiful views, and excellent service.
