How far does your "walking distance" extend to? Honestly, I'd suggest you take a few minutes, fire up Google Maps and look at the location and surrounding area and judge from there.

In my book, the appeal of the resort is that it is a bit removed from hustle and bustle which in turn means that there is no great selection of restaurants directly outside the hotel or just "down the road".

Aside from other hotel restaurants which are also sprinkled across the area, you need to make your way at least to Jl Raya Kedewatan which is a good 1.2-1.5km away on foot from the resort if you know where you are heading. Even there, the types of restaurants goes from simple "eating houses" (warungs) on the side of the road to more moderate establishments that offer a bit more amenities like air con and such. Simple doesn't mean bad of course, but it may not be everyones cup of tea so to say.

The nicer, more upscale places in and around Ubud all will require a car to get you back and forth. YMMV.
