Koblenz is the cultural hub of Rheinland-Pfalz, the town where the Mosel and the Rhine meet. The Brenner is on the peninsula that seperates the two rivers and at the point of this spit is the famous Deutsches Eck ('German corner'). It's peaceful here and you are close to the Pfaffendorfer Brüke, which traverses the Rhine, and to the monumental Neo-Classical Kurfürstliches Schloss. Despite having no restaurant, the Brenner really is a special place to stay (and the staff can tell you about more good eateries than you could ever visit during a trip to Koblenz). The rooms are decorated with obvious care, dominated by a white and gilt colour scheme. This unites furniture, walls and beds, the last swathed in crisp white linens and piles of pillows. The walls are lit with faux candles held up in crystal-drop fittings, and hand-painted with delicate floral murals. The breakfast room, where a generous buffet is laid out each morning, continues the decorative theme of the bedrooms and feels like a smart French drawing room. In good weather you can breakfast in the garden.
