Thermen Hotels in Ōiso

The location of the hotel is very good. It's facing the sea, and very near to the beach. Basically just need to cross the road to the beach. The room is clean, space is not big. For my room, seems there was not a ventilation fan in the toilet or it was not working. There was a lot steam after taking a shower. The car park is big and parking fee is 1000yen. A free spa is available for every guest. Everyone needs to pay spa tax at 150yen per head regardless using spa facilities located at 3 floor or not. A premium spa service is available at 4th floor with 1500yen charge. The breakfast is at 3200yen. Overall, in my opinion it's a bit pricey. I stayed in the hotel on 16 Mar 2024. It's still a bit cold, so I didn't have the spa even though paying the spa tax. It's a bit wasted. I wouldn't recommend this place for winter time.
