...... at the Hyatt Place, Chantilly VA.
The staff were extremely helpful and obliging. Arrived from the UK late in the evening without luggage (airline lost it) - hotel staff provided me with all the essential basics and offered to run me to the local Walmart even though that regular service had finished for the night.
The room was spacious and well appointed, the lift worked efficiently and, although the room was on the "freeway side" of the building there was very little traffic noise the next morning.
The breakfast was included in the price and provided varied options. The shuttle ran on time back to the airport and the drivers (the evening before and in the morning) were very helpful to those with luggage.
Downside: Had to call the hotel for the airport shuttle - quite a long wait.
Bar area very small and an extension of the reception desk - very little atmosphere but, again, staff friendly.
