Mike's place is a great spot for people looking for something simple, affordable, and easy. Style of the place is a long hallway with bedrooms branching off and shared kitchen / bathrooms etc. So even though it's technically "shared" you feel like you have more privacy due to the hotel / dorm style hallway as opposed to, for example, if you're staying in someone's spare bedroom.
It's a basic place but I was very comfortable and it's perfect for a short term stay in D.C. if you don't want to spend too much money. I would definitely stay here again.
