My boyrfriend and I spend a long weekend in Berlin. The location of the room is by far the greatest advantage; it is practically in the Bergmannstraße (Kreuzberg), a street with many nice shops, cafés and restaurants. In 5-10 min walk to the U-bahn Mehringdamm to visit the rest of the city.
We lived in Berlin before, so we knew a bit beforehand what we wanted to visit, however, if you are new to the city...Kaddi was so nice to make a folder with lists of places she likes to go to. Really nice overview and well explained! The room was clean and there were some simple snacks and some water on arrival which made us feel welcome. Although we did not speak or see Kaddi that much, we felt really at home/roommate vibe.
