Translation of observant 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.
The bus driver drove so quickly and with extremely dangerous maneuvers. We were so afraid and the other passengers started to scream at the driver which did not help the situation at all.
Please tell me more about you and I would love to chat with you in either English or German. My phone number is ++++++. Please call me during the evening hours. Looking forward and take care
