Conveniently located as part of JR Nagasaki train station, this is a great hotel to stay if you value ease of getting around. The tram stop is only a short walk away and you can walk to Nagasaki Port and even to the central Chinatown area in under 30 minutes. There is also a decent mall attached to the hotel/station with good variety and plenty of dining options.
I had to catch a train from Nagasaki up to Fukuoka which was easy to do after checking out of the JR Kyushu Hotel and walking the short few hundred metres to the entrance of the train station.
Like normal Japanese hotel rooms, room is basic but very usable with the standard modular bathroom. It would be a bit tight for 2 people especially if they have 2 large luggage to navigate.
