$263 Million...small potatoes

So, I have been looking at buying a place, with a budget of max $500,000.  I stumbled upon this little gem of a place.
3 islands near Positano...I just wont even consider it if the Helicoptor is NOT included.  I am pretty sure its a resort and not a private home, since it says there are 19 bedrooms and it looks like a restaurant on one of the terraces.
