"Ac was the same as it was across all of Japan. It wasnt cold but it wasnt hot. They had a dyson bladless fan in the room if you needed air movement.
My last day i reserved a cab and the staff at the front desk was very helpful in informing me that i could check out and wait for my cab in the lobby so that i wouldnt miss the cab driver when he came to check with the front desk for my availability.
Over all this is a fantastic hotel also you can get all the way to shinjuku train station underground/under roads (to avoid the rain) from this hotel.
I will mention for those who are traveling to Japan for the first time from America. The room which was a single bed was just a little wider than the bed was so it can be tight for larger luggage but i had two 28" tall checked roller bags and a massive back pack with me and still felt like i was able to get around within the room ok. If i had shared the room with another person with their luggage i would say a twin bed room might have been a wise choice.
The location of this hotel with its proximity to the train station (3 blocks or so, probably a half mile makes it great for tokyo tourism especially if you have a rail pass and can jump the trains whenever youd like to go see more of tokyo. "
