This was a perfect base for exploring Boystown and the northern end of Chicago. The apartment was immaculately clean and the bed very comfortable. It's an older building but the heat, hot water, etc. worked just fine. If people in the building were noisy, the sound would certainly travel, but I didn't have any trouble during my mid-week visit.
The surrounding neighborhood is super friendly -- I particularly enjoyed the Replay arcade bar on Halsted and the Two Hearted Queen coffeshop at Roscoe & Racine, which is like a grandma's living room. The Chicago Diner serves up a mean veggie burger. The train is only a block away, and some major buses run up Clark St.
I would certainly consider staying here again during future visits. Thank you, James!
