The apartment is in safe blue-collar district of Berlin. The furniture is modern but sparse. It was great to have coffee and milk supplied.
We stayed in this apartment during a (very) hot spell in June. The apartment did not have air condition and opening of windows was not a solution as the intercity and S-Bahn are within 200 yards (al night0). We managed and this would only be a problem for the few days of truly hot weather in Berlin (but who knows with climate change:)
The rest of the amenities was excellent ! The check-in and out were exceptionally easy
and the staff very friendly. For a few Euros we could park our car safely in the Hinterhof.
