I think this is very liveable provided that you have your full accommodation paid by the employer. True, you won't be driving the most expensive 4x4, but if you're coming w/o major debt, 16,000 should afford you a weekly evening out w/ drinks, a nice holiday each year, hym membership, and some savings. If, however, you fall prey to the lifestyle, you could easily spend 5,000/month on car payments for a fancy ride.

Whether or not that salary is fair really depends on your occupation, education, and experience. I think you'll find many western expats working for private businesses are making more like 25,000 + /month while western educated university teachers are bringing in a salary closer to your own.
