AFAIK all rooms can be booked as a single or double room, at least thatīs what the hotel staff told me. Anyhow, Iīd recommend booking a suite or a room on the Bellevue floor.

When I stayed at the Vier Jahreszeiten two months ago the Virtuoso amenity included:

- full breakfast: continental buffet + egg dishes, meat, pancakes freshly prepared upon request
- 3 course dinner at the Jahreszeiten Grill: salad (appetizer), fish or traditional schnitzel (main) and "rote gruetze" (berry pudding) as dessert (drinks not included)

Maybe the amenity has changed?
