I was in Dulles for business for a night and decided on the Hilton Dulles location-close but not too close to the airport (IAD). Overall I really enjoyed my stay. I only mention the front desk staff because they were the first part of the hotel that I came in contact with, and it seemed like I was bothering them. Note to any service people-just because someone is wearing a sweatshirt doesn't mean they should be treated like a degenerate. But whatever-I only had to deal with them for 10 minutes max so who cares. I asked for a room away from the elevator, and boy did I get what I asked for, which was great. Room was spotless (I was on executive floor), nicely updated, huge TV, free water bottles, bathroom was what I would want in my own home, so that was a great surprise. Cardinal restaurant was pretty decent hotel food for dinner-crab cakes were average, but truffle risotto was to die for. Onion soup was delicious-hearty and just what the doctor ordered after a yucky day in airports. Very quiet night, no loud road noise, bed was pretty darn comfy. Breakfast was included with my rate at the Ox grille buffet-the food covered everything you could want-eggs, pancakes, french toast, egg whites, sausage meats, muffins, bagels, cereal, fruit, juice. Pretty well stocked. Morning desk staff was wonderful, extremely helpful and accommodating in spite of having a lobby PACKED with people. I would definitely stay here again.
