Nam was a extremely impolite guest, all the time in a bad mood. As you can see in other comments, everybody enjoy to stay at our place. It is humble place, but is very cheap.
Nam was the miser kind of guest, who wants to pay very cheap and have the comfort of 5 star hotel. My room is very cheap and is a prived room with a price of hostel 10 bed room for a couple.
I did't give him my comment in his profile because I didn't want to harm him, but I had to write my response here in order to make my point.
Stay in a Hotel next time and pay the fair price for what you are expecting.
