Great for a long stay of more than 5 days. The kitchenette is very well equipped and there's Trader Joe's across the road so you don't have to eat out every day, which saves a lot of costs. The location is also perfect, you can walk, use the bus, hail cabs, or use the Foggy Bottom metro. I've done all of the above. Highly recommended and I will stay here again during my next visit.
