"Amazing hotel. I got the cheapest room, so the view from my window was an adjoining wall, but the hotel is built on a hill, providing dazzling views of Nagasaki. Splendid place.
As to drawbacks, my only complaint is that it is located in an area without nearby restaurants, bars, or even convenience stores. The same isolation that makes it so quiet and grand also means it'll be a fifteen minute, minimum, walk to any businesses.
So you do need to be signed up for the hotel's meal plan, or else carry any drinks or shopping home to the hotel on the hill."
