We stayed in Marsh's place for the weekend. It's a studio apartment in a great location in Georgetown, which is what we were looking for. When we arrived I noticed there wasn't any coffee for the following morning so I walked to Wawa on the corner and bought a bag. I messaged Marsh and he promptly refunded the money I spent.
The futon couch isn't the most comfortable to sit on, but there are two kitchen chairs and a bench at the foot of the bed. You can hear the neighbors on occasion and the jets flying over, but the noise didn't bother us.
Marsh was a great host and stayed in contact to make sure we had everything we needed. We will stay with him again the next time we're in D.C.
