I enjoyed my stay at the Shimoda Prince Hotel. If I ever go back to Shimoda I would consider staying there again.
Pros: The room was big and comfortable, and based on the layout I think all rooms have a ocean view. My room had all the desired amenities, including a mini-fridge, towels, and even a rack for hanging clothes. I enjoyed the men's onsen. The breakfast buffet is good, although expensive. Fortunately there are some small restaurants nearby that offer affordable, tasty meals.
Cons: As other reviews have pointed out, the maintenance leaves something to be desired, and the hotel can be rough around the edges. Also, the food is a bit expensive.
