Translation of nutty in German

We sat on the balcony and saw that the hotel had even a pool on the roof top but I did not have the courage to jump in. It just looked to dirty and as no one was in there I did not need to be the first.
It must have taken them years and ten's of thousands of workers to accomplish the tasks of constructing such spectacular compounds. We took many pictures and walked back to the taxi.
We left town and drove around the lake. Around 30 minutes after leaving we had a flat tire, which I changed immediately. That was very annoying as the rental company asked us to fix the flat tire.
