You will notice that it is a city filled with crack heads, beggars and homeless people. That is the bad and ugly side which I thought I should mention even though it remains a city I have never been sorry to have made my home. You will be hit up for money when you go to and from work if you work in Union Square like I do or around Market Street and the Civic Centre. Nothing dangerous though as they are very armless, but I still recommend you avoid it as well as Tenderloin at night.
Sky high cost of living is something else to adapt to when you move to San Francisco with high rental prices and overall will you find everything else like food and consumables extraordinary costly. Thus before you accept a job make sure you get a higher salary than your previous job in a quiet and inexpensive little town. Something else I must tell you is that there is always something great and cool happening and it’s a city filled with extraordinary views.
