My husband and I visited Biberach on a business trip (husband on business, I was on vacation!) and his company booked this hotel/bed and breakfast for us. On first arrival, it was a little confusing; only the manager speaks English (all other employees seem to speak only German), there's no obvious parking lot, and there's not even an apparent reception area when you first walk in. But with a little high school German and pantomime, we quickly got things straightened out, parked the car in the adjacent (minuscule) garage, and headed up to our room.
Lovely, clean room with wood floors and typical European bed: firm but very comfortable twin mattresses pushed together to make a large (not quite king, but bigger than queen -- they'll call it a double) bed, and individual duvets. (We like this set-up so much that we're considering it for home!) Pretty spacious room with wardrobe, TV, desk, en suite bathroom with kind of a small shower stall, but well-ventilated and warm (we were here in winter).
Breakfast was EXCELLENT -- scrambled and soft-boiled eggs, bacon, cold cuts, cheeses, muesli, granola, yogurt, fruit, bread and rolls, spreads, juice, coffee and a great selection of tea. Lovely bright breakfast room where everyone greets you with a "guten morgen!"
Room was cleaned every day, free wifi was reliable on laptop although not on our smartphones, location very central to restaurants and shops in Biberach -- walk everywhere! Highly recommended; we would stay here again.
