We rented the cottage for a longer working visit to Maui, but unfortunately had to find a different place when we discovered the internet wasn't fast enough for us to work from the cottage (we'd emailed with the owner before booking, but there was some confusion about what the internet service offered in the area vs. what they actually have in the the cottage, which is basic DSL). However, the owner was very understanding and let us leave as soon as we were able to find alternative last-minute lodgings that met our needs.
It's a cute little cottage -- very basic, nothing fancy, but thoughtfully provisioned, with little touches like a bucket of rag towels for messes and tablecloths for the indoor and outdoor tables. I personally really dislike 100% polyester sheets, which the beds both had, but I understand some people don't mind. It wouldn't be a great place for two couples that want privacy at night, as you want to keep your doors open at night to get the AC into your room. That said, it's nice and quiet at night for good sleeping.
Overall I'd definitely recommend the cottage as a great spot to stay in Paia, where there aren't many places to actually stay in town. Being able to walk into town easily to enjoy the shops and restaurants and music is lovely.
