This hostel has clean and cozy rooms at less than 5 minute from Friedrich Strasse station.
You can borrow towel at 2€.
And the reception staffs of St Christpher Inn Berlin Mitte are very kind and patient!
I caught my baggage lost at the morning I arrived to Berlin, and the staffs did called to the airport I used and transmit company again and again instead of me because I was inconfidence at speaking English.Thanks to them, Finally I could hang out my baggage.
