This Berg is one of a pair named the Hostile Brothers located high above the Rhine. You really do stay in a castle, watched over by the Suits - of armour. Konrad and his little brother at breakfast time, for example. If arriving by train at Kamp-Bornhoefen station on the Right Bank of the Rhine, the staff offer a taxi transfer from the station to the castle. I recommend their offer be accepted - the hill is steep. The Rhein Steig footpath runs right by the front entrance; Cruises on the Rhine can be taken from the pier at Kamp-Bornhoefen, towns on the Left Bank such as Boppard can be explored via the ferry (passengers and vehicles) a couple of kilometres downstream.
As may be expected in an old, old building, not everything works perfectly. Your warm shower might suddenly turn hot - or go cold. You might have some flies accompanying you for meals, or moths trying to get into your room if you have the windows open and lights on at night. But these characteristics are more than compensated by the friendliness of the staff (some do speak English), and the romantic ambience - both outside and inside. And if you come here from outside of Germany, keep an eye on the flagpoles - you might see the flag of your country flying in the breeze

We stayed a night here on our walking tour along the Rhine. This is a great stop if you really want to stay in an old castle - in many castles most rooms are in new sections and you do not actually stay in the real castle part.
The views of the Rhine are stunning but there is some train noise. Our room was small but nicely furnished in the period. No TV or phone in rooms. No lift so be prepared to walk lots of stairs.
Dinner was included in the rate and we were served a very nice meal - drinks were extra. Suits of armour in the dining room add to the atmosphere. Staff are nice but have limited English.
Breakfast was fine with a selection of food on each table rather than a buffet. I do not think that there was any expresso coffee available. You also ned to be aware that it is cash only for payment.
All in all, this was a unique stop in a hotel full of character.
