Let's begin, shall we?
I really like to stress this one out. I know this will not make much of an issue if you have a clear goal to yourself to just earn and send money back home. However, for me I find it so degrading. Living in a room with five double decks and putting curtains around it for your privacy. No room for you to sit and relax. Basically you are living in an overcrowded place and if you are less lucky like I am you can get a room full of bed bugs and infested with roaches.
