Agree with the first part about less condos being "more desirable".Less condos more desirable with or wothout balconies. especially in 5 star living.
I don't know how great the air exchanger will be, nothing replaces a window or balcony especially on a higher floor you always get a breeze blowing in, also a window comes in handy when cooking to let the smoke and fumes out, i can't imagine a smoker living in a unit with a window that doesn't open ewww. Trump and Four Seasons buildings both have windows that open by the looks of it.To me the Balcony and no outside space: Just huge. A deal breaker in fact for me. I don't know how many think like me. Ability to get some fresh air (despite that Ritz may have absolutely perfect air exchanger systems) is important to me and perhaps others
