Stayed there in 2016 and I have to say I had the polar opposite experience to this review. I found the staff plentiful and attentive, very flexible on keeping food for later if I didn't feel like eating at the set times. The food was incredibly varied and a high standard throughout and most of the other facilities were absolutely on point and not broke down or anything like that. Certainly wasn't loud music 24/7. I was staying there before they had an app, so I can't comment on that, although I was given a number to call (there is wifi throughout the whole island) in case I needed anything. The bars were introduced as self serve or "call the staff" if needed.
Maybe things have changed a lot (for the worse?), although to be fair (flicking through some other articles on the site, particularly the ones about Japan) this author doesn't come across as particularly pleasant or easy to please either. Maybe I'm not blue blooded enough
