Great location for us, but we don't mind a good walk. Just a couple of blocks from the National Mall. Once there, you can usually find a scooter or bike and then use it to get around. Clean rooms, Excellent staff! We felt very welcomed to be there.
Do some research on parking. We were quoted over $60 to park with Holiday Inn. Found a parking garage for $18 a day. It was the exact same garage! Also told by attendant at the garage that on weekends we could park on the street for free.
