This place has an excellent location just a block and a half from the Capitol South metro station and walking distance from the National Mall. The keypad made check in very straightforward, and the guest book has lots of great information for making the most of your stay. It was very clean, with nice amenities like snacks and filtered water. The bed was comfortable, and the water pressure in the shower was good. The only challenge was the early trains that go by every 15 minutes or so starting around 6-6:30am. Some of them sound their horn when they pass, so if you're a light sleeper then don't expect to sleep in. Otherwise, this is an excellent spot and we'd absolutely recommend it. We plan to stay here again.
