I fully recommend this place. It is clean, warm, safe, quiet and in a very good location. Zana is also a great host. It is perfect for a single person or a couple that don't spend much time in the apartment.

Great shower.

For my own liking it is too close to tourist areas that don't represent the true Berlin but that is a personal choice. However, there are very few amenities like supermarkets or affordable places in the area.
