What a terrific apartment!
When arriving at the apartment, we were welcomed very friendly. We got the keys, paid the 100 eu deposit and got lots of tips where to go.
Also when entering the apartment, it felt directly as if we were in our own apartment. The location of the apartment is perfect. Close to U-bahn, restaurants, shops and all you need for your nice stay at Berlin.
We enjoyed it fully! Thnx Trudy!
Oh.. and of course at the end we got our deposit for the keys back. :-)

One little remark... WiFi in the apartment is a Vodafone Public WiFi, which was not always working very well. Connection is there.. but sometimes extremely slow. But again.. this was a minor issue.
