Ideal spot. Nice and close to the main Nagasaki train station. They have bikes and ebikes for rent. And they have a great cafe underneath. Somewhere between a hostel/capsule hotel. Pretty ideal. Great view from the roof as well.
Lovely place. Bathroom was clean and staff were welcoming and accommodating. The stairs up to the room are very narrow though, so be cautious if carrying large luggage. Didn’t get to try their breakfast but I imagine it’s amazing. Very pleasant hostel.
