This is a really good-value accommodation - in very good condition, very clean, and well provisioned. It was perfect for our family of five and a dog.
We thoroughly recommend it.
The location is in a quiet and pleasant residential area with a small park immediately adjacent.
Central Berlin is reachable by train (less than an hour) or a straight-forward drive to the plentiful parking options (approx half an hour).
There are various small restaurants/kiosks near the train station (10 mins walk) and a newly refurbished Edeka supermarket (five mins drive).
Note : contrary to the info we received, I can confirm that there IS a CO detector in the apartment
