Hi JK:
Sorry for slow reply.
Maybe try Wing of Fung Wong Holiday Bungalows in Shui Hau, nr Cheung Sha; I stayed there lately, and seems he also rents long-term.
Good guy I reckon; as well as Cheung Sha, also near a more “hidden” beach facing Sokos.
Bit far from restaurants/shops, but can’t win em all.
