Room Cleanliness: [5/5] The room (as well the entirely house was extremely clean)
Friendliness: [5/5] Both the host and her husband are absolutely the loveliest. They are so sweet, extremely friendly and accommodating.
Value: [5/5] The price was worth the visit.
Communication: [4/5] The host and her husband can only speak in Japanese and Chinese, as well as very basic English. So communication might be an issue. However, the host has kindly printed cards and instructions in English/Chinese/Korean to facilitate any questions you might have. I could speak Chinese so that was fine, but if you can't speak Japanese / Chinese, having conversations would be difficult.
Location: [3.5/5] The location mentioned in the listing can be a little misleading. It says 25 minutes to Shinjuku Station. However, that isn't the location of the listing. That's the location of Hikarigaoka station. The train station is located 20 minutes away from the listing. So in reality, it'll take 40-45 minutes to get to Shinjuku from the home.
I stayed at 馬淵’s place for 3 nights with my girlfriend. Getting to and fro from the house to the staiton was very tiring. It's a 20 minute walk and its not an enjoyable walk especially in Winter or Summer, or after coming home from a long day out.
However, apart from location, the house, the room, the host was great and my girlfriend and I enjoyed our stay.
