With the accomodation covered, that is a good package.   Rents here go up all the time so with your employer finding and paying for the accomodation, you won't have to worry about constant increases in rent that will eat into your savings.

 

Novita is spot on with the recommendation about the schools.  Coming from the USA I would assume you are interested in the American School of Doha and it is tough to get in, especially if you have elementary aged kids.  Registering now for the next school year is the best bet but even then there is no guarentee.  My company has lost some good candidates because school openings were not available.
