One soon gets used to what "cramped" means when staying in Japanese hotels of this level, but I found this even more cramped than usual. Two things highlighted this: the dining room/space, which was badly equipped and too small for the number of tables it needed to accommodate; and, the absence of any stairs that could be used instead of the single elevator. The variety of food for breakfast was actually quite good, but it was difficult to appreciate among the crush!
While 10 minutes walk from the station, versus 1 minute for this hotel, I would choose Route Inn over Ace because it has everything Ace doesn't, including an excellent dining room, lots of space, and stairs, not to mention lots of parking. (I stayed here for 3 nights before moving to Ace.)
