I LOVED staying here! The cabins are so charming and spacious! They’re pet friendly, as is all of Idyllwild. The mayor is a golden retriever after all! The porch was so lovely and we enjoyed drinking our morning tea out there looking at all the pine trees. It takes all of 1 minute to walk into town from the property and it’s by my favorite restaurant! We enjoyed the pie we bought from the wonderful receptionist and couldn’t have asked for a better place to stay! Also, the beds were so comfortable!! I can’t wait to come back!

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.
