Nice apartment, a little far (20 min by U-bahn) from Berlin Center. The apartment was on a very quite street and free parking just around the corner.
All 4 beds were high quality for adults, the bunk beds very wide at least 90 cm- and the apartment well equipped.
Only draw-backs was that it was a rental apartment hence you have to buy dish-washing soap, sponge, salt, pepper - basically everything except toilet paper and bathroom soap. And there was places to eat near buy, but not so many.
We managed and enjoy our stay in this apartment.
