Great location right next to Takasaki Station. Hotel staff are friendly and get you checked-in quickly.
The rooms are decently sized by Japanese standards..they have a closet that can accommodate a suitcase, plus extra room between the bed and window for storage.
It's pretty good value for the price, and is a great place to stay when visiting Gunma. There are also direct trains to Tokyo from Takasaki Station, making for an easy commute into Tokyo if you have a JR Rail Pass.
