We had a great time in Katie's apartment! It is spacious and well-equipped, with everything that you might need. Brookland is a lovely neighborhood, with a lot of interesting places (e.g. Alice's jazz and cultural society is just a couple of blocks away), and with the subway, it's not very far from DC's center.
Katie was a great host; she gave us a lot of useful tips and responded quickly when we had any questions.
All in all, highly recommended!
