Translation of mottled 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.
I was very busy during the last month. I had to write some letters to find a new job. Thanks for your message yesterday evening! Where do you life in the USA? I have never been there, not yet, buy I will one day.
Although we shared the ruins with about 3000 other tourists, it still left an amazing impression.
