The hotel is just a 100 metres from the North station exit. Check in is usually after 2.30 but leave your luggage at reception and grab a meal at many of the restaurant close by. ( Especially McDonald's if that's your thing)
I would especially like to thank Goto San for her help and kindness. She gave great information for an awesome parade that morning which I would have otherwise missed.
Upgrade to a twin room and the size is huge. I certainly was glad I did that. A very nice stay at this hotel.
