Apartment outside central HK area?

Hi all

I'll be moving to Hong Kong from Ireland around the end of July to take up a job in Hong Kong Central area.

I'll be working in the Healthcare industry so pay is adequate but not excessive. I have looked at the various options for accommodation and the prices are eye-watering. I will be looking for somewhere reasonably priced (max HK$15K pcm). From my research, living outside the central HK area seems to be the way to go.

I'll be looking for a 1 bedroomed apartment within an hours travel from Central with only 1 interchange but ideally direct. The MTR seems very efficient so somewhere on this network would be great. I’m also open to other options but keeping stress and hassle to a minimum is near the top of my list.

I’m also looking for somewhere quiet and peaceful so somewhere with greenery or water views would be a bonus. Some of the islands look really nice.

Can anyone advise me what would be suitable area of Hong Kong to explore?

Thanks.
