The place is as described by other visitors and exactly what we were looking for - quiet. Alice was a nice host even offering to send us by post a forgotten charger after our departure. Communication was easy via WhatsApp.
We have found a nice bakery on the way to subway where we used to have breakfast. Even we used the app only for sleep it is equipped also for cooking, TV, wifi.
Definitely we recommed Alice and her place for a stay in Berlin.
