Absolutely lovely. The pacing was smooth, the characterizations spot-on and your descriptions - dang, I'm so jealous of this passage:
The old leather lounge-chair was empty when he entered the room, as were the battered table and chairs staff ate at to escape their patients. Harry took in the scratched, grimy surfaces, the sunken cushions, the smudges of dirt around the handles of the lockers, the greasy countertop that housed an urn, the empty packets of sugar and unwashed mugs.
Am I strange that I find that so beautiful? A wonderful story!
