Condominium Hotel with Panoramic Hot Springs - Grandview Iwai
Chiba Prefecture/MinamibosoBreathtaking views from 40 meters above, resort living with a fully equipped kitchen.
A condominium Hotel with a scenic Onsen located 40 meters above ground. All Rooms are equipped with kitchens, cooking utensils, and tableware, allowing guests to bring their own ingredients. From the scenic bath on the top floor, you can enjoy a panoramic view of the majestic Boso sea, refreshing both body and mind. Additionally, we offer Rooms with sea views, including Japanese-style and Western-style rooms. Dinner delivery services, such as boat platter meals or orders from nearby restaurants, are also available.
This was my third stay. I stayed in the same Room with a kitchen as last time. The Room had been renovated and was very clean. In the evening, we could see Mt. Fuji from the Room, which made my mother very happy. For dinner, instead of ordering the boat sashimi platter we had last time, we took out sushi and ate it in the Room. Dinner is served in your Room here, so you can relax without worrying about others. I wanted to take it easy in the morning, so I chose no breakfast. If you want a hearty breakfast, I recommend booking a plan with breakfast included.\nThe beach was quiet since it was before Obon. There were lifeguards on duty as well, so it felt safe. Unfortunately, perhaps because it was after 3:00 PM on the day we went, the beach huts were closed. It rained the next day, so we gave up on going to the beach—but students from some school were swimming even in the rain.\nI’d love to come back to Iwai for another beach trip next year too.
Yahoo!トラベルユー... 8/9/2026I chose this Accommodation because I wanted to stay somewhere with an ocean view.Honestly, I wasn’t expecting much beyond that, but it exceeded my expectations in a good way.Both dinner and breakfast were delicious.You can see the ocean from the Room as well, and if you’re lucky, you may even be able to see the Miura Peninsula across the water, the Izu Peninsula, and Mt. Fuji.It was still some time before summer, so the beach wasn’t very crowded, but we could walk to a shoreline that will probably attract swimmers.
