I wish I stayed here the whole time I was in Tokyo instead of just before my flight, it was really good. Amazing big room with nice view, shower could have been fancier though, as usual for Japan the breakfast buffet had a subpar selection of continental foods, but otherwise I loved my stay here. The self check in system is silly, if you are the only ones there checking in and there are 5 staff bored waiting, just do it for me, it's quicker and simpler for both of us.
There is also no conbinis in the immediate vicinity that are open during odd hours, but the hotel has some vending machines... I think I will stay here again even if I don't have a flight the next day! It was rare for a tokyo hotel to have an actually nice room
