Markus is very good host. He had kept welcome note and small gift in the house; felt pleasant due to this. He is always reachable on phone and quick to react. Apartment is exactly the way described here. It was very clean and all the amenities were present. For a family it is very comfortable. This was the first time my family stayed outside hotel when on vacation and they were very happy. Its very close to U-bahn and Tram stops and in the city center. Most of the attractions are close.
Only thing we didn't liked was: check-in was delayed as cleaning was in progress. But Markus had made alternative stop gap arrangement.
