This place was wonderful! We took a trip to DC and honestly we'd stay here again. It is just close enough to everything where you can walk to just about anything or use public transit to avoid driving/parking. Yet it is also far enough so when you come back it's nice a quiet. In my opinion the apartment is a great size for a couple or a family if you have younger kids that are okay with sharing a sofa bed. If you need something more this will most likely be too small for your needs. There is ample street parking but you have to check when the street cleaners come so you can move your car. It is different depending on what side you're on so make sure you don't read the wrong sign!
Around there are plenty of places to shop around the apartment. Several groceries stores some general stores others specialty so you can really shop for your needs.
The apartment is extremely close to the DC streetcar, which was free during our stay. You can take that from the AirBnB to Union station and get just about anywhere within DC and just beyond. Travel time for the streetcar/metro took about 30min to 1 hour depending on where we went. Of course you can always drive or use lyft/uber. The streetcar runs pretty late, you'll want to check because it does change on the weekends, but it's nice because you can really enjoy H St without having to worry about parking.
Overall, the place was clean, quiet, and centrally located.
Dan is extremely responsive and is very helpful and thoughtful and really made us feel at home.
