USA DC near Pentagon City

It offers an unbeatable view of downtown DC.

If you're not staying at the hotel simply walk in, take a short flight up steps to the lobby, and walk towards the elevators at the back. Take it to the top floor and you'll see conference rooms that offer this view. 2 of these times I was shooed away by maintenance just as I got my tripod setup. If you're staying at the hotel there are several room options that offer you this view.

There is limited parking along the street if you're not staying at the hotel.
