8/10 Good

"The property was nice and modern. All amenities were in working order. Location is further from center of town. The town is also deserted, almost. Nothing really around. Onsen water is nice as well as the low temperature sauna."

Karuizawa Club Hotel Karuizawa 1130 / Hewitt Resort

10/10 Excellent

"Large rooms, kind staff. Amazing price"
