My wife and I stayed at the Hampton Inn for two nights during the last weeks of March and found it to be a comfortable, modern and clean hotel.
From the moment we stepped through the door to the reception the staff were incredibly welcoming and warm and offered no end of advice.
Our room was spacious, clean and bright and the bathroom, which had a bath / tub, much to my wife's liking, had everything we needed.
In the morning the hotel offers an inclusive breakfast, which was good, and as we left the hotel for the day we were given a small lunch / travel bag which included an apple, muffin, biscuit, mints and water, so something to keep you going during the morning or drive.
The hotel didn't offer an evening restaurant service but if you showed you hotel key in a number of local restaurant you could get a 10% off your bill.
If I had one criticism it would be that the rooms do not have a personal safe which is something that most similar hotels have as standard and a facility I would have appreciated. At reception they offered to store safely anything that I wanted to give them but it's not the same having to go to reception every time you need your laptop etc.
If / when in the Manassas area again I would definitely consider staying at the Hampton Inn and recommend to others.
