Indeed, "Superhotel" to be called in my own experienced. It was a seamless checked-in when I arrived at the hotel and added plus is checking-out at the Front desk is not anymore needed, you'll just get out of the hotel with your luggage. Their sustainability support on our mother earth is there 1st priority with all their hotel facilities and guestroom's amenities. They called it "1 eco", from tissues that are being used for guest set-up to the recycled water being flushed-out from the toilet are sustainable for the environment. They have pillow menus selection on what you prefer to sleep-on and you may get it beside the reception counter. Daily amenities of your choice were just placed beside the pillow cabinet also by the reception that you may freely grab depending on your daily consumption. The hotel has welcome open bar counter (whisky, gin, vodka, soju, sake, sodas and other drinks) that you may drink (Mon-Sun) 6:00pm to 9:00 pm) located at the 1st floor. Breakfast selection are impressive, continental breakfast for westerner( daily freshly baked pastries, croissants, bagels and others Japanese food). Everyday food varieties were changed and really delicious. The two ladies assigned at the restaurant are very commendable. Kudos to both of them who are always doing an extra-miles services and indeed an extraordinary one . The hotel is 3 minutes walk from JR train Otsuka station. I highly recommended Superhotel Otsuka for my friends & family.
