Rooms were well sized and immaculate. Onsen was vey nice and not crowded. Meals were good with very good ingredient and service. Commic
Great Staff. Great food. Love the tea space where you can put your foot under the warm table. Even you can’t have your onsen, you can attend the workshop to make a beautiful photo frame with wood.
This was an unique experience. The hot spring bath, the Japanese traditional room overlooking the river, the kaiseki dinner. It was such a wonderful and relaxing experience. I wish we stayed 1-2 days longer. Highly recommended beautiful place.
Staff were very kind and respectful. Room was clean and spacious. Room had a gorgeous view of the river and trees. We enjoyed the very authentic traditional Japanese food served at breakfast and dinner. The public onsen is fantastic and the area also includes a sauna and a cold plunge. Be aware that guests with large tattoos are not permitted. Would not recommend the Japanese traditional room for guests over 5’8ft as the doorways are very low. My boyfriend had hit his head numerous times. Otherwise, our stay was great and would recommend Kai Hakone!
Property cannot service western travelers, lack of language is a big problem , it is not a luxury property with some nice spring pool and clean rooms , food variety and quality poor appeals only Domestic market, transportation is a problem also with limited taxi and hotels does not have shuttle, I ended up paying a $1 for boiled egg for my son which they refused to accommodate 2 days and finally agreed
Bell’albergo, non si può avere un caffè a colazione , orari rigidi per fare colazione come in ogni albergo in Giappone. Premetto che la cucina giapponese è la mia preferita Ma la colazione dovrebbe essere flessibile dando la possibilità di ordinare un caffellatte e un ovetto fritto, piuttosto che un brodo e tanti piccoli assaggini. Grazie comunque, le terme sono spettacolari e la stanza pure.
Before making reservation, I've sent email to the hotel if they can provide us porter service because there are total 7 adults and 3 child with a lot of luggages due to 11 days of trip. Ms.Kaori replied me yes they can provide me porter service so I made reservation and also reserve taxi for the guide at 20.00 who stay nearby since 17Sep. After reservation, I keep contact with the hotel about this to ensure everything is smooth with Ms.Eri and Mr.Rei.
One the day of arrival 18Dec, guide reconfirm with the hotel again but was informed that no proter service and no taxi until 22.00. What happen!!...The hotel keep confirm me these kinds of service until 2 days before arrival. The hotel inform me that it's call center at Okinawa who confirm me not the hotel. I don't belive that I heard this from the hotel in Japan. Fortunately, the hotel took small truck to help our luggage but no taxi anyway. I have to ask for another hotel where guide stay to pick up guide instead.
I don't know what happen but you should explian better than this.
워낙에 유명한 호시노 리조트라 묻지도 따지지도 않고 갔습니다.
룸컨디션, 직원들의 접객태도, 인테리어의 디테일 모두 훌륭합니다.
하지만 7-80만원 하는 료칸에 딱 대욕탕 두개만 있다는것. 식사가 보여지는것 만큼 훌륭하지 않다는것이 아쉽습니다.
이 값이면 그냥 전통적인 료칸에 갈 것 같아요. 한번 경험하긴 좋지만 두번 가지는 않겠습니다.
The Ryokan was full of old world Japanese culture and traditions but with an updated elegance. The grounds where beautiful in the mountain country setting of Hakone. The hot spring baths where well kept, clean, and had upscale amenities. The staff was so polite and pleasant. As you drove away up the drive they would stand at the entrance and bow to you until you left sight. We will never forget our incredible stay!!
The resort was beautiful! The staff was incredibly friendly, helpful and accommodating. The standout for us by far, was the beautiful onsen and view! We had a great stay!
Perfect architecture and decor as a modern ryokan with traditional flavor and details, especially highlighting local wood craftsmanship. Food although not as great but still good
