To get in you have to ring by "Gotthardt".
The room has 35 square meters what is a lot. There is a external monitor you could use for work or whatever. The closet is filled with my stuff but you can use the empty commode or cabinets. The traffic on the day could be loud when you open the windows, if they are closed you will here nothing. You are very central in Berlin. Perfect access to train, bus (20 sec footpath) and underground train. I removed the most personal stuff.
