"受付カウンターの裏に書類や物が山積みで汚い。部屋のエアコンはすごい動作音、外もうるさく、部屋に耳栓が　置いてある。ベッドは硬く畳の様。風呂の湯だけはラドンと天然温泉で素晴らしいが、風呂の掃除もされておらず、石鹸シャンプーは４席に一つ、とにかく人がちゃんとやればできるところが全くされておらず、これで素泊まり二人で１９０００はボリすぎ"

La Vista Fuji Kawaguchiko

La Vista Fuji Kawaguchiko

10/10 Excellent
"This is a spa hotel. They ask you to change into, not expected to, lounge/spa clothing which once passed the shock,was lovely. Onsen on site was extremely nice. One thing I will say was book dinner as soon as you arrive or before as we tried to but the restaurant was full and everything else was closed as it was a Sunday, so no dinner for us. The alternative was to wait for supper at 22:30 for ramen, which we did. Breakfast was superb and faultless."
