Julian's place is like a service apartment, the room is clean and big enough for one or two people stay. The room has its own kitchen and bathroom, coffee machine. The supermarket is 2 mins walk. The train station is just outside of the building. The tram is also just 2 mins walk, few numbers of trams take to different locations, it is easy to get to anywhere. As I stayed for 3 weeks, there are cleaning ladies cleaned my room and changed all the towels for me once a week. There is a reception in the lobby, Julian works there, he is so helpful and patient with all the questions that I asked. The cleaning ladies are so sweet, they also helped me with the coffee machine. It is really quiet, very good for sleeping. The location is safe too, there is a security man works at night, so it feels very safe even I got back quite late at night. Over all I am very happy with the stay at Julian's place! I will book again if I visit Berlin in the future :)
