Staff was very friendly. The area is very rundown and dirty. It’s unfortunate to pay hot spring tax and not be allowed in with tattoos.

2월 2~3일 1박 머물렀습니다. 호텔 가기 이틀 전 잘 하지도 못하는 일어, 영어 섞어가며 전화로 셔틀버스를 예약했는데, 아지가사와역 열차 도착시간에 맞춰서 호텔셔틀버스가 와줘서 편하게 갈 수 있었습니다. 침대는 편했고, 1층 로비 매장에서 야식으로 간단히 먹을 수 있는 간식거리와 맥주도 팔고있네요~~ 온천은 물온도도 적당하고 매우 좋았습니다.ㅎㅎ해수성분이라 그런지 부력이 있네요 ~ ㅎㅎ 특히 동해바다를 바라보며 즐기는 노천탕은 정말 최고였어요.! ㅎㅎ

のんびりする旅には最高の宿

日曜日泊だったこともあり、非常にゆったりと過ごせた。露天風呂付きの温泉、海と山の眺望（幸い天気良くて、海に沈む夕日もあり）、十分満足できる食事、建物は新しくはないが清潔で居心地の良い部屋、等々、不満は皆無でした。

訂房時沒有選擇包晚膳的Package, 心想它們有多間餐廳可以有其他選擇, 但意外的是所有餐廳全部祇提供與有買晚膳package的客人, 沒有提供散餐與其他住宿客人。唯有在小買部買杯麵解決而房間祗有暖氣沒有冷氣以９月天氣就比較奇怪，打開窗戶才空氣流通到, 其他都尚算滿意。
