This was exactly what we were looking for in our visit to the Rhine and surrounding areas. The owner was extremely responsive and the neighbors quite helpful!
The rooms have very nice views overlooking the Rhine and are very quiet at night. Occasionally, you will hear boats and trains, but it is generally quite a nice and quiet location.
We highly recommend walking back to the open cable car nearby and walking across the park above the town to the closed cable care down into Rüdesheim. You can also do a circle tour in the other direction with a river boat ride included.
So many castles and wineries to visit in the area! We enjoyed as many as we could while staying at this delightful location.
