The general level of comfort in the room and the hotel as a whole is superb. Our junior suite in the new part of the hotel was stylish and spacious and there are varied lounging areas around the building for a quiet read or a drink.
Food is as good as you will find in the best a la carte restaurants. The breakfast buffet goes from muesli to excellent, individually-cooked omelettes via fresh fruit, cold meats and smoked salmon, pastries and cakes. Five course dinners are a treat, with salads, soups and imaginative starters preceding a sensible choice of meat, fish and vegetarian options, mostly with an Austrian slant and puddings that aren't too heavy. Afternoon cakes, though not strictly necessary, are pretty good too!)
The wellness area, never over-crowded, offers saunas and similar steamy delights and the small pool is pleasantly coo (bring towels from your room.)
None of these things came close to spoiling our holiday, but if you're looking for perfection:
Rooms have no tea and coffee or ironing facilities. The pool is a little small for swimming. Rooms on the river side of the hotel, which seems to be all of the new rooms, get constant noise from the river, which some might find soothing . . .
