Todd and Candice have a great little space. You cannot beat the location. My cousin an I stayed for a quick overnight and it was walking distance to all the major sites. Check-in was smooth and communication with the hosts was easy.
I would not recommend staying here with a dog, despite the dog-friendly listing. There is a dog(s) in the apartment above and between the running across the floor and barking, they might rile up your dog. I did not expect this to be an issue, but I left my pup in the apartment for 4 hours to tour DC and was informed by the host that the barking and whining was unrelenting. Dog-tolerant, yes. Dog-friendly, no.
Aside from that small hiccup, if you are looking for a good value, cozy place (with an absolutely incredible shower I might add), that is centrally located I would definitely recommend staying.
