This was one of the best experiences of our life. The staff was very kind and helpful. The food was perfect and the onsen/outdoor tub was amazing. I would give more stars if I could.

Fantastic Excellent place to stay , attentive staff , beautiful room, delicious food and 24 hour reception came in really handy as our flight was super late and we arrived much later than we thought . Our driver was worried there was going to be no one to open the door . The phones were off in their offices as it was after hours but finally we got there and there was someone waiting for us.

Sharing our experience in the hope others will find the information useful. We spent two nights here. Three key observations.
SERVICE
Bluntly the service was nowhere near good enough. Throughout the stay. A number of staff were clearly trying their best but it felt like we were being looked after by trainees. Three examples: on arrival we waited for 25 minutes in reception, with no one else waiting, no check outs or other check ins, with almost zero information or updates. The only contact with the sole member of staff was when she came over to us and said 'you have booked dinner for 7.30, it will be very busy, we advise you to re-book at 5.30pm'. We said no thanks, not least as it didn't suit us but also as we'd booked 7.30 many weeks before (as it turned out it was almost eerily quiet at 7.30 ... one wonders whether they were trying to get all guests seated in that single early sitting). She then returned 10 minutes later to ask if we were sure whether we wanted fresh towels every day (bear in mind we hadn't even checked in at this point). We asked to book a cab to the local (Odawara) station on departure. We were told it was 'very hard'. We were subsequently told it was taken care of, but then - over the following 6 hours, including twice at dinner that evening by two different hotel employees - we were asked, 'do you need a cab, today? tomorrow?'. These are the simple things, the small things that should be automatically removed from guests' list of worries. But they wer

Exceptional service and facility.
A bit outside of Hakone but a great location for folks who need to stay away from the city and people. The small town/ Sengokuhara is also great - a ton of museums and good restaurants. All walking distance.

A beautiful stay. The private onsens were our main draw and they did not disappoint. The room itself is huge with a large balcony. The decor is so calming. The shower is lovely. The staff and all the meals were so interesting with wonderful presentation. We loved our stay.

This was the first time for my husband and I staying at a top notch Hoshino resort!
The experience of approaching and entering the building is a memorable experience by itself!
When we arrived by a taxi at the resort on Nov 14, we are greeted by the staff outside by the gate, and she helps me with my carry-on and lead us to the reception area upstairs with an impressive escalator.
The whole space inside the common areas, our assigned room and the garden outside are meticulously fantastic. As an architect myself, I could say the whole place is an amazing architectural experience which heightened your senses!
The staff is very courteous and the service is impeccable, which reflects the quality of such a resort.
It is without a doubt the best experience for such a highly rated resort!
The quietness of the place when experiencing the whole resort from the moment we arrived to incredible dinner and breakfast time, until we checked out, I believe it is due to the well planned and organized space and highest level of staff. From the moment you enter the reception area and waiting for our room to be ready, it is so quiet and peaceful.
Our apologies to only give you a 4 star, only to get your attention. The one star is taken off due to the fact that while everything else in our room is impeccably clean, the shower glass doors however was probably unintentionally forgotten to get cleaned, as those glass doors still showed water marks from previous use.
