Sorry to burst your bubble friend, but the more you learn about it the less it will probably match with what you are imagining in your head tbh. Having gone there, I can say, the place is literally just a giant resort zone with some slums surrounding it for the workers. The resort areas were constantly flooded with thousands of Chinese tourists, it was hard to even walk there. A lot of people were coming to look at the older colonial architecture also (the slummier areas) so even those areas with all their little narrow roads like the one in your picture were sardine-packed with pushy Chinese mainland tourists taking selfies.
It would maybe be a cool town during some off season maybe, but I was under the impression that I was there offseason-ish? So idk.
