You're in the heart of the Mehringdamm area, so it's a vibrant, amazing district but sufficiently removed from the main street so that the apartment, located in an inner courtyard, is quiet and shielded from the street noise. There is a full kitchen too. Communication is fast though not always the most understandable. The wifi wasn't working for many hours when I arrived (supposedly rare) and needed a router reset and Britta was helpful in guiding this via messages. Overall, it's a decent place, quite expensive for a single person stay (but so is everything else in Berlin, thanks to Airbnb having driven up local prices). Also, note that the keylock to use is the lower of the two (the check-in instructions, always automatically translated into English, are not always very clear).
