Douglas is a stellar host and is worthy of the highest marks when it comes to communication, helpfulness, and response time.
The space is as described: it's a fun aesthetic, and is very clean (a little too clean w/r/t cleaning products used, it was overwhelming to breathe). It is close to the White House, if that is important to you, but you can't see it from inside the space. The place itself is very walkable to Dupont and Logan Circle areas.
I knew that this space was on the first floor of a building, but I don't think it was fairly disclosed that it backs up to an alley--an alley that was consistently noisy, and which was at times occupied. I was pretty thorough when combing through the reviews of this place; no one mentioned that. It didn't rise to the level of feeling unsafe, but left me uncomfortable. The building overall also doesn't read or feel "residential." There are several businesses that operate on other floors of the building which is noticeable and loud.
