We recently stayed at the Presidental Inn on Joint Base Andrews. We have always found the staff to be helpful and pleasant. We have stayed here on numerous occasions because it is located close to the National Harbor area and the downtown DC area. Over the years that we have stayed here we have never had any problems with our reservations. The rooms are nice and big with a queen size bed, small fridge, coffee pot and microwave. Also, staying at the Inn lets you use the on-base dining facility. Breakfast for 2 for about $5.50.
