As always we had a wonderful experience. We left our car at the Doubletree in Sterling for our departure from Dulles Airport. This time we had to leave our car for almost 3 weeks. We were not concerned at all. We were sure our car would be safe and of course be at the Doubletree upon our return. I booked online, but had to call the office to confirm my reservation. The person I spoke to was helpful, knowledgeable and very reassuring. Thank you for your wonderful service. I will continue to use you in the future. In fact, I have a trip coming up in December and have to book a reservation. I will contact you soon. Thank you so much.
