Congrats on ur new job if ur interested to take it! lets see, a 1 BR would cost anywhere between 3500 to 4000 pm unless u prefer to share, gym also should be 350 to 500 pm, and travelling every 2 to 3 months - only possible if u work with Qatar Airways tht too if d flights r not full otherwise am not sure which Co. gives u a option to travel like tht.
Transport too costs here, anywayz all d best whatever maybe ur decision.
