If you are looking for actual schloss' or burgs (castles or palaces) to stay at, Schloss Engers is not one of them. It seems to be pretty much just an event hotel. The outside looks fantastic, but there was not much to the inside at all (at least for regular guests). The breakfast was good and sufficient, but that was maybe the only highlight. There was nothing special about the rooms. It is not in an easily accessed location (far from the highlights of Koblenz). And the price was definitely not worth it. If you are looking to explore Koblenz or stay in a palace or castle, I would not stay at Engers. If you are looking for an aesthetic place right on the Rhine for an event, maybe it will suffice. But overall I saw nothing special about the place.
