We loved staying at Janet's place! A few highlights:
1) The studio faces a lush garden, which made having breakfast on the patio outside really pleasant
2) You are walking distance from the amazing Hideaway Beach. Highly recommended!
3) The residential complex where the apartment is located has a concierge service that can help you book activities. Janet also gave us the phone number of Christopher, a private concierge you can text 24/7. He helped us find amazing restaurants and great poke. He was incredibly responsive and really helpful when planning our days. In general, you should still try booking restaurants (Eg. Bar Acuda) and hikes to the Napali coast before you get to Kauai, because they sell out fast and walk ins are not accepted.
4) The kitchen was fully accessorized. We spent Thanksgiving there and could cook a nice meal without missing anything.
One thing to be aware of (as shared by others): there is a common hallway, so sometimes we could hear neighbors. It didn't bother us, but the apartment is not secluded, if that's what you're wishing for.
