I spent 3 nights at the Hilton Garden Inn Fairfax as I had a two day session with a customer in nearby Centreville. After some research, I opted for this hotel as it seemed to be the best option a 20 minute ride from the offices. I didn't have a car and had to rely on taxis - there's not much within walking distance of the hotel. There's a strip mall across the way with a nice, big 24 hour grocery store and a few random restaurants.
As for the hotel, it catered towards business travelers. The staff were efficient and kind and the service level was pretty good. The room was a bit nicer than a standard room - it was comfy and a little homey, not completely sterile. Maybe it's because I knew I had a few days there so I opted to settle in.
Bathroom was just ok. The products are Bath and Body Works. The bathroom was nothing to rave about but it was a good size and clean. There's an ice machine down the hall and a station to buy random food items in the lobby. I had the buffet breakfast two mornings in a row - it's $10 for the non-customized option.
I met a friend in DC for dinner one night and she drove me home, which was a 45 minute ride. I didn't realize it was that far! Traffic is terrible in the DC area so if you're looking at this hotel as your DC option, definitely look closer!
