Just came back home from a weekend in DC, Herndon VA, to be exact and had a fantastic time at the Dulles Hyatt. Service was great, clean room, quiet room, great bed. Only drawback was the poor reception of the TV and the very limited amount of stations - unless you wanted to spend $17 for a paid movie. But we weren't there to watch TV. Juliette at the front desk was a jewel, or should I say "angel". Her professionalism, friendliness and thoughtfulness went above and beyond the call of duty. Thank you Juliette and I hope you see this review. The breakfast buffet was a little steep at $19 plus tax and tip but it was very good. I would recommend getting the bed and breakfast package to save some money. We actually went to a different web site to get a better package deal than the Hyatt reservation site and got the breakfast for two for only $10 more for the both of us - good deal. Nice location and quiet.
