Suzanne's apartment is located in the heart of Friedrichshain in a very convenient location; just a 10 minute walk to the train station and to areas with a ton of restaurants and bars. The street it is on is by a park and is very peaceful.
Suzanne and her son stayed with me at the apartment. She was very hospitable and very quick with responses. The space is very clean, and the bed I slept on can fit one person. She also has two very cute cats that are very friendly (but please be aware if you are allergic to cats!).
Overall I would recommend her space to anyone traveling alone in Berlin!
