Translation of apocalyptic in German

Anyway you let me know...the rest of the days I will be busy with the course. I am Italian but I live in Wien, Austria. I have not heard back from you since I sent you a message. Do you still want to chat my friend?
We decided to walk back and explore the city on foot. It was hard to cross the streets as there was an endless flow of motorcycles and bikes. One needed to just enter the street and cross it.
At the third or fourth guesthouse we finally took a room. Of course the hot water would not work, and luckily we were upgraded to a terrific, huge room with balcony and garden. It was a very charming place.
