Mark's place felt like we had an entire apartment even though it's just the bottom floor. Plenty of room for three of us and somewhat centrally located in the DC area. We walked to different restaurants and shops (there's a grocery-chain store down the street) and took an Über to the Capitol and other landmarks.

Parking was an issue but we figured it out.

We were given privacy and Mark was more than communicative and polite. And the apartment smelled great!
