Unless you step off the plane and the entire country smells of fish (like in Japan), most Middle-Eastern countries have similar smells and various locations where you can count on the smell presenting itself.
In tight places and during the summer there will be men with really bad body odor with no shame. Maybe the women smell just as bad but you can’t tell because they are in extra layers.
The flip side is men who are heavily cologned and smoking cigarettes.
The nice hotels have the aroma of floral blossoms & canned fragrances.
The old musty hotels smell just like that…musty. Dusty, old smoke is mingled with cooked greasy food & wet carpet smells.
I’ll add to this when I catch a new whiff.
