To ensure the authenticity of the displayed ratings, we do not simply calculate an average. Instead, we take into account the review credibility and the date of the guest's stay to determine the final rating.
The hotel is pretty decent. I had a very nice stay. It's clean and the rooms are outrageously spacious vis-a-vis Japan standard. While it is not easily accessible by foot to Nagano stationl, the hotel provide shuttle service to and from Nagano station at varying times of the day. Lastly, the staff were very accommodating too. Thank you.

Really nice! Enjoyed the convenience and big room, loved the windows placement at the corner of the room too. Natural sunlight in morning and city views at night.

The hotel service was great, but the facilities are a bit old. The room was small, and the cleanliness was acceptable. Compared to the facilities and comfort, the price was a bit high.

Everything was so clean!! Even the shower head was a Refa, which was a nice touch!! I'll definitely stay here again if I'm ever in Nagano!

Shuttle bus service from Nagano Station is a bonus!
Close enough to attractions by car, parking is abundant paid 1000yen for 2 days parking. Breakfast spread is pretty good.
Only down side is that the hotel is slightly old.

The bed was to hard for me to sleep on my side even when using extra blankets.

Thank you for the thoughtful service. The hotel is a bit far from Nagano Station, so I used the shuttle bus. The driver was also very polite and made the ride pleasant. If I have the chance to visit Nagano again, I'd like to stay here. *A special thank you to all the staff at the breakfast buffet.

Everything was good, but the lack of a swimming pool was a major drawback. The shuttle bus to the train station and the partner hot springs was a definite plus.
