The host Walter is reliable and the room was clean.
However I want to emphasize on one sentence in the description: "The room is like in a loft with a curtain separated -the guest may close the curtain and the room is off limit for me."
This means there is no door. And I was discuraged to close the curtain during the nights because of the heating that would otherwise be blocked. Also don't be surprised if you get asked to answer the phone that is also in this room.
