We ejoyed our 2 night stay, clean and comfortable. Nice breakfast and staff was very helpful. We found it to be a good location to other things to do. Plenty of restaurants to choose from near by and some vineyards.

I was pleasntly surprised by this hotel. Checkin staff was attentive and quick, rooms were clean, bed was very comfortable and best, free Internet and lots of outlets in the room for chargers. It looks like the hotel has recently undergone an updating. Have stayed elsewhere in Manassas, but if I return it would be here.

Stayed here for a two week business trip. Had originally opted for Comfort Suites on the other side of 66 since it was cheaper but it was booked (that location is better for restaurants and bars that are within walking distance so you don't need a designated driver.)
Courtyard Marriott Battlefield is close to Battlefield Park and close to the highway but you don't get any highway noise. Uno's is close by and there is a $3 discount if you show your room key and you also get Marriott points for each receipt that you bring to the front desk.
The hotel is clean and rooms are well-kept. The front desk attendant named Edna was very friendly and so were the breakfast servers. Breakfast was included in my room price ($8.95 separately I think.) The breakfast selection consists of various breads, oatmeal and assorted toppings, scrambled eggs (w or w/o cheese), sausage links, bacon, hash browns, salsa, make your own waffles, assorted cut fruits, yogurt, whole, skim, 2%, choco milk, coffee, cranberry, apple, orange juices, and small canned grapefruit juice. During my stay breakfast was usually open for service around 6:15am on weekdays. There is one washer and one dryer ($1.50 per load) and the washer comes with complimentary detergent (the washer water routes through a container with a solid block of soap which then empties into the washer tub) but you can purchase detergent packs at the front desk. The pool/spa area has a lifeguard on duty so the area has rather short hours of operation and no glass or alcoholic beverages are allowed. There is a small workout area with two treadmills, free weights, and a spinner as I recall. Overall a comfortable place to stay. I had a 9AM flight out of Dulles on a Friday and DC inbound traffic is horrendous every day getting onto 66 but by leaving at 6am I got to the airport, rental returned, flight checked in, and through security by 7:20 which left ample time for a leisurely breakfast in the terminal before flying out.

I stayed at this Courtyard for about two weeks. The outside of the hotel had a California look to it (which I loved). As I checked in I was greeting by a very nice group of staff (extremely nice). The rooms were very spacious and the beds were terrific. I will certainly come back!
