Walhalla Aparthotel Potsdam

Difficult to find alley access, Google maps required. Cobbles hard on suitcase wheels. Stairs, no lift. Room spacious, well laid out, bed good, bathroom well laid out, shower cramped. Fridge, microwave, kettle provided. Central location, easy walking distance to Sansoucci Palace. Check-in advertised from 3pm to midnight, but hotel closed and locked on arrival at 4pm on a Monday. Rooms opened by a keypad. No code given. Key finally gained from a lady next door who spoke only Russian. No response to phone calls or emails from hotel until 7pm, demanding key back at a time we had booked entry to Sansoucci. Demand ignored. No on-site parking, just directions to parking buildings elsewhere in town or to free roadside parking 1.5km away. First time we saw the manager was at checkout.
