Full disclosure: we 're not really "resort-type people". Although I hadn't realized it at the time of booking, Princeville is basically one big resort community comprised of several smaller ones, ranged around a golf course and served by a small upmarket shopping centre.
One of these resorts is Sandpiper Village, where this apartment is located. It's essentially a bunch of identical two-storey apartment blocks, with paper-thin walls, full of resort-type people. Having said that, the apartment itself if nice enough, well-furnished and comfortable, with a little outside lanai, and the use of quite a nice shared swimming pool. The wifi is fine, and the kitchen facilities are adequate (even if I couldn't get the coffee maker to work - maybe that was just me). Yes, there is some noise from the neighbours, but that's almost unavoidable in such a set-up. The provision of snorkel gear, beach chairs and boogie boards was a nice touch, even if we didn't really use them. The nearby shopping centre has a reasonable supermarket and a few good cafes and restaurants. Oh, and a word to the wise, if you eat dinner too late, you run the risk of running out of unassigned parking spaces.
We never met Bob the owner (who actually lives in Utah), but he answered our emailed questions promptly enough, and check-in was easy (the key is in a key box).
All in all, the apartment makes a pretty good base for exploring the north coast of Kaua'i, but don't expect any of the individuality and quirkiness that we've come to expect in Hawai'i.
