How much is standard salary to survive in Qatar?

Please help me,
I am an Indonesian nurse, I got an offer from HMC (Hamad medical Hospital) in Doha. They offer me QR 6,800/month and they give free accommodation. Do you think this salary is enough for a single woman living expenses? because i've heard that if we want to have a decent living we need to at least be paid QR 10,000/month, is that true?. I think living and working outside is not all about getting experience, i mean, we sacrifice many things, being away from family and friends. Thus, the reward should be worth it. If i want to save a bit from that salary, do you think this is possible for me?. I am in two mind to take that offer, but i can't make a proper consideration since i know nothing about living in Qatar and about their culture.
Please fill my space of knowledge here, Thank's a bunch

Tolong bantuannya,
Saya perawat dari Indonesia, kmrn dpt tawaran dari HMC (Hamad Medical Hospital) di Doha. Mereka nawarin gaji QR6.8000 per bulan, tapi penginapan ditanggung. Kira2 dengan gaji segitu apa bs mensupport biaya hidup saya disana? saya single tapi saya juga pingin bisa nabung sedikit2 dari gaj itu... Saya juga gaktau gmn kehidupan disana, budaya mereka gimana ya? apakah aman bagi perempuan keluar rumah sendiri? apakah kita harus pake baju hitam2 dan jilbab semua?.
Tolong kasih masukan yaaaaa, masukan berupa info apapun akan sgt hargai... karena saya butuh nfo apapun ttg qatar dan seputarnya.
Terimakasih banyak......
