Mara's place is super central, at least for Kreuzberg area. We loved to be so close to Südblock and Kottbusser Tor as we could enjoy nice evening drinks and get to any place in Berlin easily with public transport. I would say that the room/place is very suitable for people who have their own plans and are independent travellers as even though we had a flatmate in the apartment we never saw them, so I guess this is super comfortable for people who like a lot of privacy. If you are more on the curious side liking interaction with your AirBnB flatmates then you might end up disappointed :)
The room has a lovely table and a view/balcony from 12th floor so that is something quite special.
