We had a great time staying here for 3 nights. The property was very clean and modern, recently renovated. Our host Kuni-san provided very detailed directions on how to get to the property, and binders full of information about how to use the appliances and other useful guides. He was very responsive to messages and gave us all the information we needed to enjoy our stay.
There was plenty of space for 4 adults and a kid, lots of beds to choose from, two toilet cubicles with washlets (heated seats, bidet functions) and two sinks, plus two showers, one with a tub. There were plenty of amenities in the bathrooms and kitchen and having a washer and tumble dryer was a bonus. The kid enjoyed chilling in the secret loft space.
The location was excellent, near several convenience stores and local restaurants, just a short walk from the Kinshicho station and shopping areas. We were even able to get a JR Sobu line train directly from Narita airport which saved us having to navigate train transfers with our baggage.
