me and my family had a very pleasant and memorable stay there. if I could suggest, I'd say to always read and follow any instructions provided, because it will help you a lot as the instructions are very broad and detailed.
the apartment may take several minutes if you wish to commute by train, but the routes taken are worth it as it takes you away from the bustling roads, leaving you with nothing but a peaceful atmosphere.
moreover, the host is also extremely cooperative, with almost instant replies for any questions you need to ask, yet providing descriptive and detailed informations with great hospitality to follow.
that is, if you are looking for a reasonably-priced and peaceful place to stay in Japan, this will be the place to be.
