Translation of cement 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 seemed that the fisherman and his daughter did not intend to keep on rowing unless we would buy something and we were really annoyed by that and did not hide it. In the end they passed.
Nice to meet you. Your German is not bad at all, stop being so insecure. I have been learning Spanish for 3 weeks only. I am visiting a private Spanish teacher. It is very expensive but good.
