The Hilton Garden Inn in Fairfax is a good choice if you plan to stay in Fairfax, Virginia.
It is not very far from Dulles Airport.
The prices are reasonable, especially if you reserve ahead of time. It is quite, the rooms are comfortable and the service satisfactory.
We stayed here in January 2013.
Nice choices are available for breakfast.

This is a great hotel. We found it back in the summer of 2008. We were in the process of moving to the Fair Lakes are of Northern Virginia in Fairfax County. We either called or just drove right up and I think the rate was under $100. We stayed just one night.

Over the past few years, the hotel has kept up the high standard you expect from a HGI.

The rooms are very clean. The beds are comfortable (and I'm picky about beds).

Though my main point about a hotel is the room, I have to say that the breakfast is outstanding. It’s cooked to order, and all you can eat of the cooked to order items, as well as all you can eat of the gourmet buffet items. The breakfast is so good; I have been back many times to eat since moving to Fair Lakes. I'd say paying $10 for a cooked to order meal is one of the best deals in the area.

Seems like they run a shuttle to the metro (subway station). It's located off of Highway 50 / Lee Jackson Memorial and is a few minutes from I-66. Its 20-30 minutes from Dulles Airport and 30-45 Minutes from D.C. (but take the subway to D.C. and avoid the traffic on I-66).

Ask for AAA rates, Govt, and etc. The service here is outstanding.

My daughter and I stayed at the HGI Fairfax,Va. January 5th,2013. We got lost on our way there,I called the hotel and Jennifer talked me there the whole way...Finally when we arrived we were greeted by Jennifer at the front desk with a huge smile! It was a rough day, we were very tired. She was cheerful and helpful. She gave us the phone numbers of all the food delivery places in the area(as we were starving!), She advised us of what the hotel had to offer us during our stay. She was great! The hotel has an inviting foyer with a welcoming fireplace,and comfortable sofa's.Also-FREE Starbucks coffee and tea's! Delish!!! A full service restaurant, snack area and a small convienance area. Indoor pool! Our room had 2 double beds..sooo comfortable..huge rooms,beautiful clean bathroom comfy chair and desk area. They have a fridge and micro and coffee maker. Besides my own bed this bed was the most comfortable I have slept on!!!I You wll love this hotel. We travel ALOT and are very picky about where we sleep. We felt safe and comfortable.I will definatly stay there again!

I have stayed in at least 5 different hotels in the Chantilly-Fairfax area. This HGI is by far the best of those I have tried. Room was super comfortable, with reliable Internet service. The bathroom was sparkling clean and well-appointed. Breakfast was terrific, with eggs made to order, cereals, fruit, juice, pastries, etc. The staff was outstanding -- so friendly and pleasant - they act like they really enjoy their jobs. Everyone I met greeted me warmly and helpfully.
Stay here. You will love it.
