I stayed at this hotel for one night while showing some family around the area. I will note that I used Priceline for this hotel and received a great rate. One thing about using Priceline is that, if you require a handicapped accessible room, you should call the hotel and ask if they can provide you with one. If not, you can contact Priceline for a refund. The hotel at that point should be able to give you a 'yes' or 'no' answer when you call so that a decision can be made.
When I called to request a handicapped room for my father, the hotel told me that this would be possible. Upon check-in, they informed me that a handicapped room was not available and that since we booked through Priceline, they would not be able to make a special request for the room.
Location: The hotel is immediately off the Herndon/Chantilly exit of the Dulles Tollway (VA 267). Standard airport location, many other hotels around, chain restaurants, shopping center down the road.
Hotel: Looks good. There is a small alcove across from the front desk with a TV. There is a decent business center, fitness center, lots of meeting rooms and a pool. Parking is free and plentiful. There is a shuttle to get you to the airport. If you have a room on floors 4-7, you will have a long walk to the far bank of elevators.
Room: Large and clean. The room looks like it has been renovated. Flat screen TV's, nice furnishings and bathrooms. The beds were comfortable. Wi-fi internet is free. You get a small bag with earplugs, eye patch. Rooms have a microwave, fridge and coffee maker. I really have no complaints. Holiday Inn's parent is working to make sure that there franchises are meeting certain standards and I think the rooms are solid.
Restaurants: Houlihan's is on the ground floor. They also provide room service. The food is expensive, but pretty standard Houlihan's fare.
Overall: I liked the hotel and thought it was a very nice property. Ultimately, the room my father received was not completely unacceptable. The doorways accommodated a wheelchair and the bathroom was large enough. Had they been more upfront when I initially called, I would have been happier.
