Hotel Sunvalley Izu-Nagaoka Honkan - Izu 4-Star Accommodation

Reviews across booking sites repeatedly praise the 'excellent onsen' and 'variety of baths'. Buffet meals are tasty with many options. Clean rooms and kind staff are also positives. Some highlight great room views.

However, some note the facilities feel dated. Complaints include poor room temperature control making it hot or cold, non-opening windows, shared slippers, and lack of convenience stores.

Suitable for travelers seeking onsen and dining experiences.
