Translation of vano

Hans was not in the office for 4 days. I informed him that it is urgent and asked him to send it by tomorrow morning. I'll do my best that you receive it as early as possible. Trust me on that.
Nevertheless I think that we need to communicate. All in all, we will learn a lot from each other, mostly by writing, but speaking exercises are also really good for your Spanish skills. Is this OK?
We woke up around one hour before arriving and got off the train once it arrived at its destination. We checked in for our last night in the same hotel very early in the morning after having coffee of course.
