It is hard to believe this is a 2.5 star hotel in terms of quality. The decor in common area and in the room is done very tastefully. The bed is very clean and comfy. Big screen TV, fridge and microwave. For some reason, Expedia searches don't show this place when you search for Reston/Herndon/Sterling, but Hotwire does (after you prepay the stay, of course).
This is also one of the few places that offer both wired and Wi-Fi access. Internet access is very fast either way.
The only complaint I have is the room's layout. The air-conditioning console is right next to the work desk. When it's on, you may feel big winds blowing on your face while you type on your computer. Meanwhile, the dresser, TV, fridge and desk are all against the same wall. So you can't watch TV while you at your computer/office desk.
This Inn is right next to local highway but very quiet - it's actually next to a big shopping plaza so shopping is convenient.
