16K is a decent offer.
you can get a single bedspace starting from QR350/-
if you have a family and looking for family accomodation you can have a 2bhk around 4,000/-
the daily ost of living isnt very expensive .
A family visa needs to be atleast 10,000 riyal , but you are being paid 16,000 so you can lead a decent life,(with a free car).

Mabrook and welcome to Qatar.
