Our family spent four nights at this Hampton Inn during our trip to DC in March 2013. After researching numerous hotels in and out of DC proper, we decided on this Hampton Inn for its price (about $100 less a night than hotels in DC), parking cost (half the daily rate of DC hotels), and proximity to the Metro (5 minute walk). The hotel was quiet, and we never heard other guests while in our room (this was a concern because of the school groups staying there during our trip). Taking the Metro in and out of DC was a breeze, and our kids loved doing so. The Hampton Inn is also within walking distance to many restaurants and the Crystal City Shops.
I definitely recommend this hotel. Our family will probably stay here again when we return to DC.
