The hotel was very good in some ways- clean and quiet (especially rooms facing inner courtyard). Breakfast was poor (especially the hot breakfast) and poor value, but coffee good. Kettle in rooms would be useful. The hotel was literally on the wrong sides of the (rail) tracks. Although close to station, route via underpass, and quite some distance from old town and River (but half hourly 60 bus route). Staff tried to be helpful but some requests were not responded to (including emails before stay). In short, fine if you want clean hotel near station, but less appropriate for best parts of Mainz.
