5 Stars from me. Great spot. Stayed here a little under 3 months.The room is exactly as pictured. I will say that if you are taller than me(5'10"), you might hit your head if you're not careful(It is an attic room, after all), but the room is spacious enough to where it is not really an issue.
Convenient location in regards to public transportation. Busses are very close (<5 min) although I didn't use them, and metro about a 15 minute walk. From the metro station, you can get downtown in about 20-30 minutes depending on exactly where you want to go. 3 minute walk to a massive Safeway and a 5-7 minute walk to CVS.
Self check-in is super easy. It uses a pretty straight-forward keypad that you will receive a code for a day or two before your arrival. If you ever need anything or have questions, Jon is extremely quick with responding. The neighborhood is nice. I walked a lot to Rock Creek Park, about a 15 minute walk away, where I would go running a lot. Lots of families, people walking their dogs, runners, bikers, walkers, etc. I may eventually move to the DC area permanently, and this neighborhood be an option for me.
Roommates, although I didn't really interact with them much, are super chill and welcoming on the times where we did talk.
