I really liked the Kamakura Prince hotel. Some may say it is dated, but I think it had a classic mid-century modern/art deco look which I thought was great. The staff was very friendly and helpful. The rooms were comfortable and clean. There are two restaurants: (i) a Japanese teppenyaki restaurant; and (ii) a "European" restaurant. I would not say that they are super gourmet, but I enjoyed my meals there. The European restaurant has huge windows looking out over the water with views of Mt. Fuji and it is phenomenal at sunset. I gave the hotel 5 stars because I really liked it, though it is not a true 5-star hotel like a Ritz Carlton, etc.
Also, in case this matters, it is about a 10-15 minute taxi ride to the center of town. It is set outside of town in a nice area overlooking the water, but it is not in a walkable area, in case that matters.
