How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

TV position looks good to me as is. All you need to do is bring the sofa in the center of the living room - and facing the TV unit (see how much space are you getting around to walk) You can have a nice central rug and dazzling chandeliers / hanging lights above the sofa set. The wall opposite entrance can be your feature wall because it faces the entrance so everytime someone enters , they will see that wall first and it should create an impact. The feature wall ideas include - Have a beautiful Mandir there ( I don't know what the Vastu is of the flat so plan accordingly) or make it a nice reading nook with a lazy couch / chair and a lamp or planter . If you don't wish to do any of the above then make an accent wall - have a very quirky wallpaper backdrop and have two high back chairs with a coffee table. you can have innovative hanging lights on any one side. If you want to increase utility of your house then you can also have a sofa cum bed there - which can be used by guests / friends etc.

I think next time onwards any company should not respond to these kind of postings without any floor plan, requirements and budget.
