This is a decent place to stay with great access to central DC and all of the attractions. The apartment is in the basement, not on a ground level, with no outside light. But unless you are spending time here, it's not a problem. It has a very nice kitchen with all you will need. A large bathroom, and two good sized, comfortable bedrooms. There is a sitting area with a small table for dining, not a living room per se. The whole place was very clean with nice bedding and towels.
There is an issue with the back bedroom, however, because there is a small window at the top of the wall that connects with the bathroom. This means that when someone turns on the bathroom lights (very bright) it floods the bedroom with light. Not good in the middle of the night. This can be easily fixed and has been recommended, but if not, bring eye shades. Sound is not a problem, neither from the street nor upstairs.
There is a small mini-market next door with a few things, and a large supermarket two blocks away with everything you could need. Some good restaurants within a couple blocks. Uber and Lyft rides quickly appear in front when called. Very convenient.
The host was very kind in allowing us to check in early due to a meeting schedule. Communication was sometimes slow, but it did happen and there were no problems. It's self-entry via code, and we did not meet the host.
