Denis is one of the friendliest hosts we've ever met. He received us with very clear instructions and guided us around his place and the facilities available. We arrived several hours before the check-in time, and he was kind enough to save our luggage so we could go out to explore the city in the meantime.
The location is just perfect. There's a supermarket very close and the train station is located at just 10 minutes walking from the apartment. From the train station you can easily get to Berlin Center in 15 minutes.
The room has everything you'll need, the bed is cozy and very comfortable.
The neighborhood was very quiet, and we felt pretty safe, with lots of nature around.
We definitely recommend staying with Dennis while visiting Berlin!
