Martin was very accommodating of my last-minute changes and was very cheerful and welcoming. The room was very basic but bed was very comfortable.
Things to note: bathroom is shared with other guests and is tiny but good water heat & pressure and is clean. The place is on the 4th floor and the 3 flights of stairs you have to walk up are filthy. Martin's place is pretty clean so don't let this discourage you, just be aware. The room has transom windows that open to the living room to let in AC so is not super private.
