My family and I had a great time staying at Jon & Tanya's place. It had everything we needed, with thoughtful touches including a welcome basket (the pirate booty made my son incredibly happy!) The unit is exactly as described and what the pictures show. Jon was very quick to respond to questions or offer great dinner suggestions. The unit is very convenient to all the major attractions and some really great restaurants as well. We were able to walk everywhere we wanted to go and the location felt safe.
The only downside for us was that the AC unit in the living room is LOUD. It would turn on every 10-15 mins and was between 82-85 decibels high. It made watching TV difficult as we had to keep cranking the volume up and down. Other than that, everything else was perfect and we enjoyed our time in DC.
