Hotel Description
You know what struck me first about The ISO by Castle? The name actually makes sense once you’re there – it’s got this sleek, almost minimalist vibe that feels intentionally designed, like someone really thought about every detail. I mean, it’s solidly in that four-star sweet spot where you’re getting genuine quality without the stuffiness of those over-the-top luxury places.
Honestly, the 7.9 rating feels about right. It’s one of those hotels where everything works the way it should – the key cards actually open doors on the first try, the shower has proper water pressure, and the WiFi doesn’t cut out every five minutes (which, let’s be real, is rarer than it should be). The staff seems to actually know what they’re doing too, not just going through the motions. Check-in was smooth, and they had that perfect balance of being helpful without hovering. The rooms have this contemporary feel that doesn’t try too hard – clean lines, decent lighting for getting ready, and thankfully no weird carpet choices that make you wonder what happened before you arrived.
What I really appreciated was the attention to those little things that frequent travelers notice. The outlets are actually positioned where you need them, there’s enough counter space in the bathroom for your stuff, and the blackout curtains actually block light. The noise level was pretty reasonable too – you might catch some hallway chatter if you’re a really light sleeper, but nothing that would keep you up. I stayed during what seemed like a busy period and it never felt chaotic or understaffed. The whole place has this calm, professional energy that makes you feel like you can actually relax. It’s not trying to be the flashiest place in town, but sometimes that’s exactly what you want – somewhere that just does the job well without any drama. If you’re looking for a place that won’t surprise you in bad ways and delivers on the basics with some genuine style thrown in, this is definitely worth considering.

Reviews
Dzsenifer from Netherlands (8/10)
I loved the location . We had the room just in the corner by the ocean (125) just like in the pictures for our honeymoon. It was beautiful and clean. Those who complain about not being able to swim in the ocean because of the rocks. They only have to walk like literally 2-3 mins for a sandy beach but already waking up for this view and having the white noise of the ocean it’s just amazing and felt so relaxing. We are beyond grateful for the island and ISO who also made it possible to comfortably enjoy it .
Ruperto from United States (8/10)
Great location and friendly staff. We appreciated the free water bottles and the water dispenser in the lobby. They also had free bike rentals for use on a first come first serve basis. The complimentary continental breakfast was also appreciated.

The setting.
Marissa from United States (8/10)
We really enjoyed having access to the beach cruisers to bike along the oceanfront path. Grab and go breakfast was great. The location was perfect with lots of beaches close by or just being able to walk on the beach directly from the property. Staff were all very friendly and helpful
Don from United States (9/10)
Nice to have breakfast included
Lisa from United States (8/10)
The ocean view was wonderful. The front desk staff worked to change our room to make it a ground floor, more accessible, no stair stay.
Philipp from Germany (7/10)
View of sunrise, morning yoga class, bike rentals for free. Young staff was exceptionally nice and helpful.

The view was awesome. It was in a good location for both ends of the island. The staff was always cheerful and helpful.
Derry from Australia (8/10)
The room was clean, the free bikes to explore part of the island was amazing as we didn’t have a car and the grab + go breakfast was a pleasant surprise!
