This excellent hotel is a 7 minute drive from the Dulles airport. They offer a complimentary shuttle to/from the airport. The hotel also operates a complimentary shuttle within a 5 mile radius including to the Vienna Metro station (which i did not use). The suites are very spacious and clean with a bathroom in each of the 2 rooms. The kitchen is well equipped and some welcome snacks are provided in the suite upon arrival. The varieties offered for the free breakfast are wide and the staff replenish items promptly. Similarly the housekeeping is superb.
The only downside of the hotel is that local shops a re a good 15 minute walk from the hotel.
The best thing about the hotel is the staff. All staff I've met are very curtious and helpful. They really make you feel welcome.
