Wonderful!

10.0

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!

品質與收費不成正比

6.0

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。

It was a very relaxing stay. The onsens paired with the food was a great reset to daily life.

The location was amazing, the view and walk to the sea was spectacular. The onsens had wonderful views as well. The food was really good, I don’t eat a lot of seafood but there were plenty of other options.
