My husband and I stayed here due to a flight layover. The shuttle was right on time and the hotel a short drive from the airport. We stayed on the executive floor. The room was clean, comfortable, spacious, and most importantly, quiet!
The floor offers a private lounge (think living room, not bar style) with snacks, coffee and drinks at half the price of the main floor hotel bar. The woman working was very friendly and emphasized Hilton's interest in customer satisfaction. In the 30 minutes we spent there, twice guests made special trips by the lounge to personally thank her.
We later found out that she indeed deserves a special thanks because we received a bucket of champagne with glasses at our door shortly after we left the lounge. While talking with her my husband mentioned we were taking our belated honeymoon. She had called the concierge to arrange the champagne for us!
The breakfast offered everything one could want. Although you can choose to eat in the lounge if staying on the executive floor, the main floor breakfast had many more options.
We would stay here again as our first choice in the DC area.
