You will find decent accomodation in 5500 plus plus...but you have search for it as accomodation goes and comes very very fast.. i m telling you unfunished accomodation..... it can be sharing with separate entrence....but if you go for main Doha like close to airport and around it wil be expensive then 5500...but by 6000 you can get close to down town Doha...but still you have to search...
