I travelled with my elder parents and was concerned, mostly because the hotel was a basic hotel. I called prior to departure just to ensure I wasn't making a bad judgment call. I spoke to Debie who was WONDERFUL. She said, you're here for a long time (9 days) and she upgraded us to a room with a microwave and refrigerator. Red Roof was terrific - other than no breakfast options, and having to go to the reception area for coffee, as my mother said - nothing was missing. The staff was helpful and more importantly, the rooms were clean. If anyone has mobility issues, they have an elevator for the upper floors as well.
We chose Alexandria, Virginia - and it proved to be the right choice. The hotel is on the highway but incredibly close to the Metro and provided my needs beyond clean and comfortable: free parking and free internet.
