Now I realized why he is a super-host. There's a subway station(S-bahn, U-bahn) just in front of the builiding. And there's a supermarket near the house.
Clean, and silent at night, and you can see a wonderful view day and night. For the last, the host is really kind and friendly.(The security whose office is next to the front door in the building was also kind.) If you have any questions, just ask him when you check in. Danke Ivos^.^
