Would happily stay again. Clean, warm, comfortable and convenient for the museums - do not miss the Stadtsgeschichtliches above the old Rathaus; also the Volkskunde in the Grassi complex - and for the superb zoo. Eating out is pretty miserable - but the local Aldi is fine and the flat's kitchen adequate for basic meals. No washing machine, but plenty of drying space for hand washes. I would say the flat can comfortably accommodate two couples at most. Disregard the state of the street door: the apartment block itself is fine.
