This place is really great for a single traveler to the DC area. His row house is in the historic part of DC, and the neighborhood is quaint and charming to walk through. I felt very safe walking alone at night.
He is very close to both a Giant grocery, a Whole Foods, and other little restaurants that are reasonably priced and good. Union station is just a short 12 minute walk, and if you are leaving around 8 or 9 am, to get a jump on your day, just follow the other commuters - you can’t miss them!
The bedroom was private, and had plenty of space so I didn’t feel sardined after just my first night there. He has a nice little outside deck, where you can get some fresh air or make a phone call in private.
I had 3 windows in my room, which always make a space feel larger. A huge plus. And closet space and dresser space is by the plenty.
However, be aware that the bed is VERY firm - something I am fine with, but others may not be comfortable on such a mattress.
The bathrooms were spotless, and he even has some shampoo, conditioner, and body wash Incase you forget something - which I did.
Over all, he is a quiet and very courteous man. We had no issue with our schedules. He allows you to use the kitchen, and living room to your leisure, and invites you to ask him any question if you may.
