We stayed four nights, ten persons, in this amazing storage apartment, just around the corner from Hermannplatz. Sebastian was very forthcoming on our arrangements for coming and leaving. The place was immaculately clean, well equiped with very comfortable beds, nice linen and towels. The huge main room was ideal for a large group with a well stocked kitchen, a large table to gather around and small sitting groups. The two bathrooms were spacious with good showers. The wifi was swift. The walk up four flights of stairs was by some of our group seen as a bit strenous. The only thing that was missing was that there were not any reading lights by all the beds.
The location with a three min walk to U-bahn and major bus-lines just outside was very efficient. And most of Kreuzberg-Neuköln could be reached within a 15 min walk.
