Chosen for the location close to the Nagoya Castle & room- largest western style bed we have seen in Japan.
The first night, the A/C stopped working midway through the night & thought it was a mistake on our end. Restarted the air con controller & was rocking in the morning fine.
Second night, same. After going to the front desk, my limited Japanese & staff's limited English (I know I'm in the wrong w/limited Japanese)- it was explained the a/c thurnes off at night. Then tell the guests upon checkin because unless you turn off the unit overnight, it states blowing warm air- the opposite positive sleeping environment! 2nd night, he did provide a fan & we were able to make it through.
3rd & last night, turned off the unit overnight, on the fan & made it though.
Maybe go in mid-to-late summer & the a/c would work throughout the night?
