We were aware of the location is nearby the Katz Orange Restaurant however couldn't guess that it was exactly inside the courtyard! The building and the courtyard is amazing and no need to mention that the location is a central place in Berlin. Interior of the house is minimal style and everything was in order & clean. We really enjoyed about staying there and would like to thank to Klaus for his quick responses to our messages. I would definitely recommend this accommodation and of course a dinner at Katz Orange :)
