In so many ways this is a great hotel: helpful and attentive staff, huge rooms, excellent restaurant, stunning location perched above a waterfall near a river's mouth so that the splashing of water is a constant backdrop. The only realistic improvements I can think of are getting the WiFi to reach beyond the bar area, replacing the tv in the bar, and requesting Google Maps to send people the right way rather than across a (blocked off) farm track: there are signs but if you miss one or it's dark this is a proper problem.
However, I must say that the hotel isn't really aimed at solo travellers and it is a long way from anywhere else. It would be excellent for a romantic break and there are activities which could keep the kids occupied if travelling as a family... just not so much if you're on your own. This isn't the hotel's fault of course, but I think it is a fair warning.
