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.

The support from staff was very good. The shower and shower curtain was sub standard. The bathroom floor would flood, since the curtain would blow out, and shower was difficult to control. Some difficulty getting HDMI connection to TV from my computer, though good support from hotel staff.
