I stayed here for a few days last year, meeting my husband who was working across the road in Dulles.
The hotel was quiet, clean, spacious, with good food and utilities.
It literally had everything you needed, super comfy beds, all the tv channels, gym, amazing staff and balcony for watching the world go by.
Across the road there is lovely shopping mall, I truly had a lovely experience there. The most realistic looking Santa ever was in a grotto. It brought back to me the magic of Christmas.
With a huge selection of shops and food this mall is really useful. It's got everything you can need.
The hotel staff are happy to get you too and from the airport in their own car.
We used this hotel as a base over the weekend, taking one night in Washington and returning the day after. I'd recommend this hotel to anyone who wanted a base near (ish) to the airport. Probably mainly used by businesses, but still brilliant.
