The Residence Inn is a dog-friendly, mid-priced hotel near Manassas. It is only 20 minutes or so from Washington Dulles airport, and a day trip into Washington DC is easy to plan from here. (Note: the rush hour traffic into DC in the morning and out towards Manassas in the evening can be severe, so plan accordingly. Even going to Dulles during rush hour took an extra 10 - 15 minutes for us.) As for the hotel itself, it is about par for a large chain - clean rooms with uninspired decor. The hotel has a pool and other amenities. Our room was a suite with a full service kitchen, including stove, microwave, coffee maker, plates, glasses, utensils, etc. The hotel staff is friendly and they do their best to help you out. We arrived early in the morning and wanted to sleep after the overnight flight, so they found a room for us at no extra cost. Note - if you do bring your dog, there is an extra charge.
