We had a wonderful stay with three colleagues in this stunning apartment in the center of Berlin. We only booked two days in advance (something with a wrong hotel booking), and were really happy that we were helped so promptly. The information to check-in, check out, leave your luggage, etc, was also very comprehensive (perhaps even a bit too comprehensive, as it took some time before we could deduct the most important/useful information from the multi page instruction messages). We are already thinking when we would like to come back with friends or family ☺️. Highly recommended!
