Really enjoyed this place. Perfect for a big group.
Comfortable beds, really well cleaned and maintained apartment, a couple of good showers and decent kitchen facilities. Plenty of tea, coffee, etc was provided by the host.
The door code check in was provided promptly which made it easy to manage multiple group members arriving at different times and no need to keep track of keys.
The place was a short walk from the Wedding S-Bahn, so very handy to the public transport system.
Thoroughly recommended place to stay for a large group.
