The footpaths in the area are cobbled and this makes dragging a wheeled suitcase awkward. Public transport connections good. The spiral staircase up to the flat is narrow. The flat is one room with an ensuite toilet, equipped for all your basic needs including a small induction hob. The shower curtain is close and clings to you, a minor issue. My criticisms are minor as overall the location is a cosy base for one or two people visiting Berlin.
