I spent a 5 days at Reva's place and really enjoyed it. I'm a former long-time resident of the neighborhood and came back for work, and the desk set-up and wifi were great, so I had a very productive week. It's also a great location - at first I was a little worried about the alley entrance, but there were no issues at all, and there was tons of on-street parking. I had my car so didn't have to depend on mass transit, but there's an easy bus to the metro that stops down at the end of the block.
The room is very small, and might be a tight fit for 2 people if you're planning on spending much time indoors. But it was perfect for me, and I believe is accurately priced for what you get.
My one complaint is that I won't drink bottled water on principle, and also am not convinced of the quality of DC tap water. I asked Reva if they had an extra Brita filter, and unfortunately they weren't able to provide one. I filled my reusable water bottle at the local yoga studio and at friends' houses, but that would be a very welcome addition.
Other than that, the apartment was perfect for my needs.
