Mark was very helpful and his place was extremely nice...just as advertised. He provided suggestions for food and events near his apartment in Foggy Bottom. It's a 5-10 minute walk to Georgetown or 15-20 minutes from Lincoln Memorial/White House, and it was always easy to walk outside a grab a cab. Would highly recommend this place. Can pay to leave your car in the deck below the Westin Hotel just one block away. Look forward to visiting again.
