My wife and I stayed here one night. We live in Tokyo and although it is only a one hour trip by train it felt as if we were on a holiday trip far from home. The room is very spacious and had a nice view over the bay. Interesting detail: binoculars were provided to watch the shipping and view across the bay. We were able to see Yokohama's Landmark Tower and Tokyo's Sky Tree.
Although the hotel is located at sea, it does not have a beach. The pool was nice but had one disadvantage: it has small pebbles around the pool which makes walking barefoot a painful experience. And these little pebbles end up in the pool as well. Sun chairs are set up around the pool but there are barely enough chairs for all the guests on a busy day. We noticed that this pool is very popular among families with young children.
The spa is similar to a Japanese onsen with an indoor bath and an outdoor bath. There is also a sauna. I was told that the women's side had different baths and layout.
In our case was dinner included which tasted very good. You have a choice between a Western or a Japanese menu. If you would have to pay for it separately it would be a bit pricey. If you don't have a car you cannot avoid this as all other restaurants are not within walking distance (exception: Italian restaurant at the nearby museum). The breakfast buffet had enough choice of food and drinks.
All in all we concluded that most likely we will return here in the near future on a weekend trip.
The hotel is located a few minutes drive from downtown, and many don't know about it. It is a very good hotel, with comparable facilities, and dining options. Located on the water front with a great view of ship traffic to/from Tokyo harbor. Rooms are spacious, clean, and well equipped. The dining room is modern, with comfortable seating, and a great view of the shipping channel. Dining selections are very good, and include both Japanese and Western dishes.
