I highly recommend April's place, and would definitely stay there again. The location is excellent (quite near Admo, walkable to the red line at Woodley or the green/yellow at Col Hts). The place itself is clean and well-decorated, but most of all comfortable. April's thought of everything you might need, from coffee to a hair dryer to an iron to multiple pillows of different levels of softness. She also super communicative and flexible with you about bag storage if you're dealing with weird travel schedules.
Final note: I know some people commented on how it was "loud" because it's near the entry-way, but it's "loud" because it's in DC. If you aren't used to being in older, multi-home buildings or off of a busy-ish street, then bring earplugs. If you are (and I am), then you won't even notice the "noise".
