The best way to the apartment from central station Berlin is the underground U2 train to Sophie Charlotte Platz station and 250m walk. The front is a construction zone so it does not seem like the right place. It has plywood step and construction debris outside. But Nina is a warm and welcoming hostess. She gave us extra special care and targeted the most important spots for us to see on our trip since we took the long way there in the beginning and were feeling too tired. And the interior of the apartment is brand new and spacious. The large shower has ample hot water and the kitchen has pots and pans and spices and coffee and tea and chocolate. The beds are comfortable and there was even a candy gummy and chocolate treat on each bed for each person. This is a host that cares about the guests and you will receive extra special care and a great place to stay which will make your trip nicer.
