What it is like living and working in Frankfurt?

Hi everyone. I might be moving to Frankfurt for work and I would like to know abit about the city before making the decision. I will come and explore the city for a few days but from your experience, in short, what it is like living and working there? Oh and I will be there in the weekend of 19th Aug, anyone wants to have coffee and explore the city? Thank you and have a nice weekend! :)
