  • This was my first stay here with my son’s family of five. The Room felt very spacious, with high ceilings and plenty of room, so my grandchildren were thrilled and ran around happily. The small space on the second floor also had a wonderful view of Mt. Asama right in front of us, and it was truly relaxing to enjoy a drink while playing my favorite Western music.My grandchildren can be quite sensitive, so we choose our overnight stays very carefully, but this time they liked it so much that they asked me, “When are we coming again?” I’d love to return again soon.The staff were kind and efficient in preparing everything for us, and their attentive service made our stay very comfortable.It was truly a wonderful night.Thank you very much.

  • This was my second stay, and I was able to relax again this time!When I used the in-Room sauna, I took off my necklace and forgot it, but you contacted me right away. It arrived the next day, and I was truly touched that you even included cookies and coffee.I really think this is a special villa!The Nepalese staff who prepared our meals were also very kind, always smiling, and wonderful people.The Room was incredibly comfortable no matter how many times I stay.One small disappointment: the breakfast bread is delicious, but there wasn’t quite enough.Also, the large public bath used to feel like a cave-style bath before, but it has been changed to a more compact bath, which was disappointing.Thank you so much to all the staff!I will definitely stay again!
