My husband and I spent two nights in Jason's condo during a visit to DC. We had everything we needed and were SO close to the National Mall, restaurants, etc. There is also a rental bike docking station right in front of the row homes; so easy!
Jason was very prompt in his responses to our questions and was a great host. We really enjoyed staying in a homey environment rather than a traditional hotel, and I would argue that we had better location and amenities than a hotel as well.
