Terry sheets in bed in a 4 star hotel is not acceptable.
The dinner menu is far from acceptable, small or no variations during 7 evenings. Meet or fish to choose between, all fish was small thin rectangular pieces with skin on, looks exactly same shape and fabricated. Skin was soft no crust and not eatable. The vegetarian and the vegan food was exactly same dish 5 of 7 evenings, variation was tomato- or gorhonzola sauce.
Not one single dinner we got a typical dish from Austria, not even a local desert was from Austria! There was not one day with pasta or rice.
I even have to send back old ham from the saladsbufet, it smelled bad, same ham was already served at breafast and come back as mixed salad.
We decided to eat at another restaurant, when we realized that the hotel took old food and served it again. They need to change headchef and replace with creative headchef working with the menu.
Do not pay for halfboard at this hotel, eat elsewhere.
