All in all, we thought it was a very good value.
The room was accurately described, although it should be noted that it is a second-floor studio with access only by stairs. It was clean, reasonably spacious, and well located on the north shore, although not within walking distance of much, which is true of pretty much all of Kauai. It is relatively close (about a mile) from the only shopping center in the area.
The hosts communicated well, and everything met our expectations. In particular, it was very fairly priced, which is important for someone on a budget. The lanai was very nice to sit out on. There is also access to a pool, which we did not use.
The room includes a refrigerator and microwave, but there really isn't a kitchen (there are lots of kitchen utensils, including plates, glasses, cutlery, a coffee maker, etc., and a hot plate which we did not use). There also really isn't a table at which to eat. There are grills next to the pool which we believe can be used and would probably be better than trying to cook in the room.
There is a single sink outside the bathroom. The bathroom itself was fine, with a good shower. The hosts supply four bath size towels (two for the bath, two for the beach), but they are getting old and could be replaced. They also supply two beach chairs, which were very much appreciated. There is no real closet, but there are hangers and hooks on which to hang things. There is adequate drawer space for things that don't need to hang. Our only real issue is that several slats were missing from the vertical blinds on the door to the lanai, reducing privacy.
Also, there is limited parking -- if you expect to be out late at night, it may be a problem finding a space when you return.
We enjoyed our stay and would return.
