The sections where you see two balconies side-by-side should be the two-bedroom lockoffs. If reserved as a 1B and a studio, each room will have its own balcony.
The sections where you see a single balcony covering a fair stretch of real estate would be the dedicated 2Bs. Those rooms would just have the one balcony off of the living room. The flanking bedrooms would not have their own balconies.
