The apartment is in a great location in an awesome neighborhood. I found it very easy to get around, and the Airbnb itself was quaint and unfussy. Definitely will suit the needs of any other traveler in Berlin for a short period of time.
However, Nadine was not a responsive host and I found myself in a very dire predicament and was unable to get in touch with her when I needed to the most. It deeply impacted my overall experience as her guest and was very discouraging -- hopefully this is just an isolated incident.
