Customer’s live reviews

Those are actual reviews from Mi Onsen & Spa’s customers.

“골프치느랴 땀도 한바가지 흘리고 뻐근한 몸풀러 가기에 최적화되어 있네요. 목욕도하고 마사지까지 한번에 받을 수 있으니 말이 필요없죠. 운동하시는 분들에게는 최고의 코스네요!”

“태국올때마다 항상 오는 곳 입니다. 방콕에 이런시설 이용하려면 금액대가 ㅎㄷㄷ 한데 여기는 저렴하고 편하게 올수있음! 그리고 다른데랑 비교하긴 좀 그렇긴한데.. 굉장히 깨끗하고 넓어요 ㅋㅋㅋ 한국 사장님이 신경많이쓰신듯 하네여"
