The money you will need depends on your condition. Do you have a place to stay or are you planning to rent? Are you going to eat out or cook? And where the place of your work is. Anyway to put an estimated range you will need from 15k to 25k for a 3 months rent. For food and transportation you'll need about 15k to 20k with minimum spending. So I would say 30k to 45k would suffice. If you're planning to visit some places and go around the city and stuff, you are going to need a whole lot more money.
