Translation of nod in Spanish

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 stayed in this place for quite a while as it was the most spectacular place we have visited so far. It was unbelievable how much thought was put into construction of these magnificent sites.
