Me and my family had a really amazing time in Berlin, and it was such a pleasure staying in Sørens beautiful (and huge!!) apartment. It looks exactly like on the pictures, so no surprises.
The check in was very smooth and we were even able to check in 2 hours earlier (we arrived with an early morning flight) which was much appreciated. Great communication with the hosts, both before arrival and during our stay. Good instructions for our self check in, and check out was easy as well.
Overall a very great stay, and I highly recommend staying here for your Berlin trip! :)
