We stayed for a couple of months in this apartment. It is spacious and has everything you would probably need. The price is reasonable, specially if we consider that it is in DC and everything is a lot more expensive. The location is great for downtown.
Also, S. Is a unsurpassable host: she is nice, gives you great advices for DC and cares that the time you spend there is comfortable.
We fully recommend this apartment for anyone that is going to DC.
