Considering the Hotel Avantgarde in Koblenz?

Fort Ehrenbreitstein by Bigs
This fort on the other Rhine side of Koblenz might be nice viewing point. Havenīt been up, only saw it from down below. Itīs on the other side of the Rhine, you can reach it by ferry and lift or by car. Think the view over the city and the two rivers is quite nice from up there....
