I had a short but very lovely stay at Mo's place! Mo was very communicative and helpful when I was looking to check-in early, even sending me a link for a nearby luggage storage spot. The room is private and, along with the rest of the apartment, very clean and nicely decorated! The location is also in a quieter area but within easy walking distance to Checkpoint Charlie and Kottbusser Tor (the latter for late-night food options). Would highly recommend Mo's place to future Berlin visitors!
