Shifting to Mumbai Soon, need advice / help

Hey there people of Mumbai! I will be shifting to mumbai for a job in the month of April. My office will most likely be in either goregaon or vikhroli. Some of the people that I have contacted say that I can put up in goregaon itself or maybe in andheri. What do you guys suggest? By budget for rent is 20k. What options do you think I can get in that budget and also which area should I go for?
