If you want to stay in the middle of chaos (in a good way) choose Tugce's place. It is in the middle of Kreuzberg so you will find many bars and restaurants. The department is two minutes away from a station so you can move anywhere with ease. The bed is comfortable, the bathroom is really clean, and Tugce is always one message away if you need something. Be aware that the building is currently being remodeled so you will find dust on the stairway and the lights may not work all the time (I had to use my cellphone light sometimes to not fall over). Other than that, it is a very nice place to stay!
