Translation of integrity in German

The best place to eat for us was the Tamarin cafe. The atmosphere was really a backpackers atmosphere, but with style. People were sitting there with laptops and and travel guide books.
We checked in at the Hotel de Paris, a small hotel owned by a friendly, old lady. Our rooms were OK, but we asked to be transferred to the newer part of the hotel. The stomach ache of my wife did not disappear.
