Translation of bacillus in German

When we got our room at the Rex we were shocked once again. The room had a terrible smell of cigarettes and we insisted on moving. The next room they gave us was a non-smoking room.
We really felt like being in a stupid tourist attraction. The environment was very beautiful but the mass of people would ruin our special moments. Anyway we had one more surprise on the way back.
I guess it is a very interesting book, but I did not entirely understand it. What did the author try to say, what message did he want to deliver? Do you want that I recommend another book?
