The Spotlight on The ISO

Beachfront Vibes with Concert Convenience in Kapaa

Modern island style meets laid-back comfort at The ISO, a breezy oceanfront hotel in Kapaa. With its prime location just across from Waipouli Town Center and only a 15-minute drive from Lihue Airport, this hotel offers an ideal base for exploring Kauai and catching a show. Each studio has a touch of Hawaiian flair, with private patios and coffee-making facilities, plus free WiFi to plan your concert night.

Why Concert-goers love it

If you're in town for a show, you'll love the relaxed beachfront setting that’s still close to local venues. It's easy to wind down after a high-energy night thanks to the peaceful oceanfront pool and quiet property layout. Free parking makes late-night arrivals a breeze, and its central Kapaa location means you're never far from where the music happens.

Who this Hotel is great for

Groups of friends will enjoy the on-site amenities like tennis and shuffleboard courts for daytime fun.
Solo travelers chasing their dream concert will appreciate the quiet, easygoing atmosphere.
Couples can turn a concert night into a romantic beach weekend.
Fans wanting a quieter post-concert recovery space will find the ocean sounds and laid-back setting ideal.
Budget-conscious music fans will appreciate the value of free parking and included WiFi.

Food and Drink Options

The on-site Bullshed Restaurant serves up seafood and steak with a side of ocean views, perfect for a pre-show dinner or a celebratory bite after. While there's no 24/7 room service, the restaurant is open nightly, and you're walking distance to local eateries for late-night snacks. Coffee-making facilities in each room mean you’ll never miss a morning brew, even after a long night.

Nightlife Options

While The ISO itself leans more peaceful than party, it’s close to Kapaa’s low-key bars and lounges. For those looking to continue the night, nearby local spots offer laid-back drinks and occasional live music. Or, take in the sunset and sip something local at the hotel’s serene beachfront setting.

What People Say

Guests rave about the unbeatable ocean views, friendly staff, and the relaxing vibe that makes it easy to unwind. Reviewers also highlight the clean, cozy rooms and convenient location near dining and shops. The Bullshed Restaurant gets high marks for both food and atmosphere.

Areas for Improvement

The rooms are more about comfort than luxury, so if you're looking for upscale finishes, this might feel a bit simple. Some guests mention that the property could use a few updates, and that oceanfront living means occasional humidity indoors. But for most, the charm and location more than make up for it.

The Bottom Line

The ISO is a relaxed, oceanfront retreat that gives concert-goers the perfect mix of location, comfort, and chill Hawaiian vibes.

Superb

Liked: I loved the location!! It was so close to everything, including the airport. The grounds & ocean views were beautiful!! Also, the breakfast was delicious with a good variety.
Disliked: What I didn't like was the booking company I booked my reservation with....Booking.com. They misrepresented the rooms & info for the ISO by Castle. I booked & paid for a room with two queen sized beds with an ocean view right outside our room & sliding glass door, with the online photo showing the ocean view just a few steps away. They were very misleading & when we checked in, we were told by Rihana that the property didn't even have rooms with queen sized beds.....only rooms with double beds or a king size bed!! Something needs to be done about Booking.com being untruthful & misleading about their reservations!!

Good value for money!

Liked: Had everything we needed. Clean, simple. Good location, nice ocean view. Plenty of parking space.
Disliked: Breakfast wasn’t anything special, we could have done without. Would have been great if there was a pool bar / bar at the hotel to have a drink at the end of the day. Staff was friendly enough, not super welcoming or going the extra mile, but that was fine for us.

Great staff, great, views, very...

Liked: The desk staff and yoga teacher were wonderful.
Disliked: 3 stories up, without an elevator or bellman! My 75-year-old husband injured his back carrying up luggage, Day 1, and we ended up spending nearly $1000 on one massage and 5 chiropractor appointments before he could do any real walking or standing.
