My girlfriend and I stayed at Brady and Jen's place for a little over three months. They were some of the best hosts we've had. Both were easy to communicate with and quick to respond to anything we needed. They are great people and we're both glad we got to meet them.
The unit was very clean and well furnished with anything as guest would need for a stay. Comfortable for two for short term living. There's a pull out couch another one or two could stay on but that's probably not great past one weekend. It's located in a nice neighborhood in northern DC. It's a quiet, residential hood but in a quick 10 minute walk you can be on the metro or at a local bar/restaurant. Most of our favorite spots ended up being close to us so that helped even more. Internet is very fast. Parking in the alley helped out a lot as well.
If you're coming to DC for a few days or longer this is the place to stay.
