My wife and I are thinking of coming to D.C. in fall (late September/early October). We really like using VRBO or Tripadvisor and renting a condo. We've never been to our nation's capitol and are not sure what are to stay in. I'm sure like anybody, we want to be close to the monuments, dining, bars, etc... We may not rent a car so close to public transportation would be key. Any suggestions would be great. Also, how is the weather during that time of year?
