Claudia's space is a great base to check out Washington DC. The apartment seems to be fairly new and everything was quite clean. Her communication was quick and thorough, and was available at any time I needed her.
The only downside to this space that I can think of is that it is on the bottom floor of her house and its very easy to hear people moving around on the floor above you. They didn't keep early or late hours, so it didn't bother me much. Other than that, I highly recommend this place if you are single or a couple looking to explore the DC area.
