Absolutely beautiful—period. I would definitely stay here again. Iso Castle offers a peaceful, beach-cabin–like experience that is all about location, quiet, and natural beauty. We stayed in December and loved falling asleep to the sound of waves crashing and waking up every morning to a stunning sunrise over the ocean. The views are truly unforgettable. This is not a luxury or fancy property, and that’s part of its charm. Don’t expect a kitchen—there isn’t one—but there is a fridge, and everything was very clean and well maintained. The balcony experience was a highlight for us and added so much to the stay. I highly recommend booking a premium oceanfront room if possible. Rooms 233 and 234 are exceptional. A couple of practical notes: there is no elevator, so be prepared to carry your luggage up the stairs. The only downside was the service from one staff member at reception on Christmas Day 2024. She seemed quite grumpy and unhelpful, particularly when we asked to have our towels replaced, which was disappointing given an otherwise lovely stay. Overall, Iso Castle is a beautiful, quiet oceanfront retreat. If you value views, serenity, and a relaxed beach atmosphere, this place is well worth it.

Everything else is great other than the Wi-Fi connection. Can only login couple of times - even in midnight the connection fails consistently. My guess is the server only allows certain number of devices to login for the whole property. Then in the room both Verizon and T-Mobile cell phone signals are next to none. We literally had a very quiet vacation disappearing from the grid because kids even had a hard time to contact us. Hope management can invest some money to improve the Wi-Fi system.

Location was great, ocean view and chairs were nice. Room is pretty bare bones and the restaurant being closed felt like we were missing out on drinks and meals on site. Chickens will likely wake you up early each day but they were fun to watch running around. Pool was nice to hang out around outside.

The Balcony was PERFECT! I would definitely return. I would only suggest the Fire Pit stay on maybe till 11pm for us nite owls. And maybe more lighting. The outdoors blue light was nice. But maybe a few more colors for a well rounded minimal lighting experience =)
