Can you elaborate on why you find this space so fascinating? It looks like your typical floor model that is shown to potential buyers?
Also, I'm pretty sure that isn't a studio as that is a legit wall that divides the living room from the bedroom. It's not even a convertible because the wall typically can be retracted.
First of all it's a pied-à-terre you uncultured swine
Isn't it the occupant that determines whether or not the apartment/condo is a pied-a-terre? If it is a legit second residence then it's a pied-a-terre. If they are there full-time, it's just an apartment/condo.
