Apart from the comfortable big bed, clean room, and more than enough amenities, this hotel also boosts a terrific location in Nagasaki. In a few minutes you can walk to Nagasaki station. In front of the door stops the tram/streetcar, bus, and 'shuttle bus' to Nagasaki airport. Around every corner is a convenience store, various sightseeing spots are within walking distance, couple shopping malls are also nearby and a coin laundry is a few minutes away (if you feel the one of the hotel is too full).
The only thing that could have been better is that the power contacts are too close to each other on the table, preventing me from using both when using a converter (JPN->EU). But even then there were enough plugs to charge all of my devices.
And the hotel wasnt expensive at all!
The hotel changed name the day I arrived. Fortunately they removed the nameplate around midnight before my arrival ;-). It is now called Esperia or just S-peria, but the locals still know the name Chisun Grand Nagasaki.
