10 / 10Outstanding·Jul 2026
We recently stayed at Hotel Grand Mer Sankaiso as a family of three during the busy Golden Week holiday. Despite the hotel being quite crowded, we were highly impressed by how efficiently the staff managed everything and kept operations running smoothly. The dining experience was a major highlight, with both the breakfast and dinner buffets offering an absolutely outstanding variety of delicious food. We also loved the hotel's saltwater hot spring, which was a unique and refreshing experience. Additionally, there is a charming traditional hot spring bathhouse located right next to the hotel, though please note that you need to make an advance reservation to use it. Above all, every single staff member we interacted with was incredibly friendly and dedicated to their work. We would like to say a huge thank you to the entire team for providing us with such a wonderful and memorable experience!

ラウンジのロケーションが素晴らしかった🎵 露天風呂から見えた、夕日と海が綺麗で感動しました!

收費昂貴的旅館卻連基本的洗衣機都沒有、連住兩晚卻還必須自己到櫃檯拿毛巾,中間的白天完全沒有基本的客房清潔。
