    My son planned a relaxed, unhurried trip to visit Kasama Inari Shrine, Nakaminato Market, and buy melons in Hokota, and chose this Hotel for our stay. The Hotel itself may be older, but it has been beautifully renovated. The lobby and entrance are stylish spaces, and the view opens from the inlet out to the sea right in front of you—making a great first impression. The Room was also well designed with unnecessary items kept to a minimum. It felt clean and comfortable. Dinner was pleasantly healthy for us seniors, and we enjoyed it very much. It seemed a little light for my son’s generation, but the late-night ramen service is a nice touch (we missed it because our dinner was late). We wanted to enjoy dinner quietly and at a relaxed pace, but unfortunately it was noisy that day because we were dining alongside a large group of older guests. Breakfast was buffet-style with a good variety across different categories, and everything was tasty. Overall, it offered excellent value for money, and it’s a Hotel we would like to visit again.

    Since the property has been renovated, the Onsen, dining area, and Room were all very clean. The meals were very delicious. If possible in the future, it would be helpful if the yukata sash were elastic, especially after a good meal.
