The room is small and dated so don't come here and expect a nice room. I was also assigned to a smoking room and they were not able to switch me to a non smoking room. Even with windows open, my clothes still smelled of smoke. Make sure you contact them in advance to request a non smoking room if this is important.
The food was actually surprisingly good. The buffet had a good selection and tasted good. Be sure to get there really early as there was a long line and hard to get a table.
The real perk of staying here was the onsen across the street at Diachi. Highly recommended for the full experience.
