We were expecting a big house with a real kitchen as described, but is more like a guest house with a small place with not enough stove to cook. We vote sufficient because, compare to the price the service is basic.
Bernhard is a good man, a nice person, but we think he can do much more for his guests. Our tips: to provide a comfortable kitchen suitable for 10 persons, as the bedrooms suit max 10 pax, a larger fridge too (not a fridge-floor per bedroom), to fill the kitchen with essential ingredient and stuff (sugar, napkins, spoons, teaspoon, enough pans, real burner..).
There is a really nice terrace to enjoy during the evenings, on the upper floor, but is not so comfortable and cleaned, this could be improved
