We stayed for a week in Mark's appartment, which is actually a small house made into 4 appartments all rented out. The appartment is very nicely located in Foggy Bottom, < 10min from GWU and the Foggy Bottom Metro station. The house is newly renovated and well equipped, although a few things were missing in the kitchen, esp. cleaning stuff (not everything is solved by a dishwasher). The largest drawback of the house are the very thin walls, you hear every step from the appartment above and we had the bad luck that the first night a group apparently had rented the appartment to make a party until late in the night, not that nice. They should maybe pay a bit more attention to who rents the appartments and for what. The rest of the week was fine. One small problem was the cleanlyness of the floor and esp. the carpets which, obviously, had not been vacuumed in quite a while. I wrote a message and someone came cleaning the next day so it was fine. Overall, the communication went quite well and quick. The place is really nice, but there should be proper maintenance of the stuff, otherwise it's going to look run down in very little time. Overall, the stay was pleasant and we had all we needed. Would stay again, esp. since its well located for a work stay at GWU.
