Hi
I know Qatar very well, been here for a while now
Most people buy or rent cars - we dont have rail or metro
Internet and home phone costs 230QAR a month only some sites are banned, but there are VPN's that get round them
Shopping is fine
As to QR -- read the posts about the company, lay down in dark room and think again
Cost of housing has come down a two bed appartment in a ok area can be from 7000QAR a month
If you take the QR housing its not bad depending upon your grade.
