The building is really beautiful, and I think it's a relatively new property, probably built within 1 to 2 years (as of March 2021). The living room, dining room, and kitchen are very spacious and comfortable, and there are about 7 bedrooms, which can accommodate up to 20 people (the bedrooms that are not in use are locked, so if you are staying with a small number of people, you can only use the rooms you need). ).There is also floor heating, a wood stove, and in addition to the bath, there are 2 showers and 2 toilets. The kitchen is spacious and has more than enough clean tableware. Bath towels are provided, as well as amenities such as shampoo and toothpaste. There was also a washing machine and dryer. My wife washes all her clothes, ski innerwear, etc. before she packs them up, and says it's fun because she doesn't have to do laundry at home when she gets home. It was equipped with WiFi and the speed was quite fast, so I guess it was an optical line. There is no need to mention this if it has a dishwasher.We stayed with 5 people this time, and on weekdays, it costs about 40,000 yen per night for 4 people. If it's the day before a holiday, the cost will be around 50,000 yen per night for 4 people. It's true that it seems a little expensive when you just look at the price, but I think it's about the same or a little more expensive than staying at a Prince hotel.It costs 8,000 yen for each adult and 6,000 yen for each child, so the price gets cheaper as the number of people increases. If you want to take a slightly more luxurious trip with 3 to 4 families (about 10 or 15 people), or if you want to take a trip with your whole family, you can use it for a trip with friends and family (however, it is expensive, so if you want to travel cheap) Also, although the living/dining space is large, it may not be large enough to accommodate 15 or 20 people, so if you have 15 people, you can eat at the dining table. I think it will be like sitting on all three sofas in the living room).The location was also good. Harunire Terrace and various facilities at Hoshino Resorts are within 5 minutes by car, Tsuruya Supermarket is about 7 to 8 minutes away, Karuizawa Prince Hotel Ski Resort is about 10 minutes away, and the historic Mampei Hotel where John and Yoko stayed, and Karuizawa Ginza are 15 minutes away. It was very easy to move around within Karuizawa.The one difficult point was that signs such as ``Caution'' and ``Please ventilate due to coronavirus'' were pasted in various places, and I thought they were a bit noisy (in fact, they were in my line of sight and noisy). Rather, it seems like there are little warnings posted here and there. Moreover, it is difficult to understand because it is displayed in various parts. The checkout procedure was also difficult to understand, and I think it would have been easier to understand if these items were displayed somewhere or in a booklet.Also, it was a shame that there was no garden. There is a wooden deck, but it's completely visible from the road, so I didn't think I'd be able to use it for relaxing on the deck. If you could install a fence to hide the area between the site and the road, you might be able to relax on the wooden deck.Well, those kind of drawbacks are only at the level of "if forced", and I think it's a facility that should be given at least 85 points out of 100 (minus 10 points for being a little expensive, minus 3 points for messy display, sorry about the wooden deck) It's about minus 2 points).I think I'll probably use it again (to be honest, I'd be happy if you could lower the price just a little bit. It's okay if there are conditions. For example, if you write a review, you can get 10% off next time, etc.) overnight discounts, repeat customer discounts, etc.)
