This is my favorite kimpton hotel in the DC area, I've stayed at most of them. Hotel Monaco Alexandria is the best and I've stayed here several times!
Why? First, you're getting the same funky luxury that kimpton does so well. The rooms are a great size, I've stayed in both a regular room and suites. This hotel has a garage, major perk for me and you can take the elevator right up to your floor from the garage. The hotel restaurant, Jackson 20, is truly great, you must try it if you stay there! The rooms are always clean, beds are heavenly, never disappointed with a stay here.
