Jim was the prefect host. He guided me on the phone about how to get to his. Then helped us with our luggage. The place was big enough for four people and very clean. The sofabed was decent. We used the washer, dryer and the dishwasher. All worked well. Jim had 4 metro cards for us to use which came in quite handy. We arrived in the afternoon so street parking was a bit hard to find but it opened up in the evening so we were alright.
If you're visiting DC I would highly recommend Jim's place and would love to stay here again.
Many thanks Jim!
