The room was a bit cramped, making it challenging to fully open two suitcases. On the bright side, its proximity to the JR station is excellent. A heads-up: there are two Toyoko Inn hotels near Numazu JR. Don't just rely on the signboards, or you might end up at the wrong one.
The place was without fault and the breakfast buffet was very nice, the only thing I guess to mention is that there's a bit of a step from the room to the bathroom but once you know about it then it's a non-issue.
YYASUSHIA sauna and an open-air bath are available for 2 hours rental as a set. Hotel users can use it for 3300 yen.
The hotel is made to be used for love hotel → business.
The facilities feel a bit old overall, but cleaning and fixtures seemed to reach the details.
I would like to use it again because it was very good that the sauna and open-air bath could be used by rental.
