The apartment is lovely and in a beautiful location. The apartment complex is beautifully set up with a lot of plants and tastefully decorated, with friendly cats and chicken wandering around between the buildings. Kapa'a is a great little town - right at the ocean with an awesome bike path along the coast (and the apartment comes with free bike rental, so that's an additional plus!), and a lot of cute little restaurants, cafes and shops, without being overrun with tourists. Perfect. The apartment itself has everything you need, and while not very big, it is set up very economically so that it doesn't feel cramped at all. The only thing about the apartment you should know is that the bathroom only has a folding glass door between the bathroom and the bedroom. So you should feel comfortable around each other, because there's not that much privacy.
Ida gave us a very warm and lovely welcome, with a lot of helpful information, and some complimentary snacks and fruit, which was very much appreciated.
There was a bit of a miscommunication about the arrival - apparently we were supposed to get in touch with Ida ahead of time, but we didn't know this and also couldn't find a phone number or email address other than Margaret's on the AirBnB page. It's possible that we missed something, but either way, that was a little confusing. It turned out totally fine - we called Margaret when we arrived, and she in turn called Ida, who showed up right away and got us settled, so it was no problem in the end. All in all, we were super happy with our choice, and would definitely come back if we stayed in Kapa'a again.
