We stayed here in early February (on points). Great value for DC area on points. Room was large and clean. We were given a queen suite, very comfortable. Parking was only $12, in covered garage beneath hotel.
Breakfast was plentiful, fresh, and had a large selection. Don't know about evening snacks (although there was a menu on the refrigerator). We were there on a Sunday night, so it didn't apply.
You need to use your room key in the elevator to access your floor.
Fitness center was small, but we walked all over DC, so we didn't even think about using it.
Excellent location near to Georgetown, if you enjoy walking. Only about 2-3 blocks from Metro, if you'd rather take mass transit.
I wouldn't hesitate to stay here again.
