New PhD student at the U - need advice

Good morning y’all! I’ll join the U as an international PhD student at the David Eccles School of Business. I wanted to ask fellow PhD students, also from other departments for some advice.
First, how would you describe your time at the U? Is the work-life balance any good?
Secondly, how good is social life at the U for grad students? Are there any interesting clubs I should look forward to join?
Third, I plan to live on campus for at least the first year (got accepted in the Spruce residence). Do you suggest me to stay in campus for the duration of the program or is it better to move to off-campus housing?
Thank you very much for your time and help!
