Location of Largo's Residence
I followed all of the 'location site' in IMDb.. and couldn't find it. Then on google map saw a placement of a Wikiki 'W' on the map. and boom found it.. It's still hard to explain.. but the most exact way is to use gooble maps website and ck out co-ordinates Lat/Long;
25deg 04' 23.83" North & 77deg 26' 32.03" West
Hasn't changed much (surprised).. can still see the shark pool.. etc
Best luck
