Luisa's place was excellent for our trip to Kauai. Located literally a minute walk to the beach, 5 minutes to the Ke Ala Hele Makalae paved bike/run path, and super close to several excellent places for food: Taps & Hops (go during happy hour), Pono Market (get the spicy ahi poke), Paco's Tacos (the best al pastor we've had), etc. Convenient drive to the north or south of the island.
The apartment was well equipped with essentials for a day at the beach or a night in. Luisa was super responsive and accommodating. We had a Wailua river kayak guided tour booked on the last day which finished after the check-out time, but we were allowed to leave all our luggage in one of the closets and pick them up after we were done.
The only possible complaint was that one of the bedrooms was kind of stuffy if the door was closed (the living room AC didn't reach all the way). Otherwise, amazing stay and we wish we could have stayed longer. Highly recommended.
