I found Hikari’s place to be very clean, comfortable, and perfectly sized up to 8 persons. The location was great. The nearest station was Hatsudai, one stop away from Shinjuku. Hikari was attentive. All my questions were replied within few minutes.
However, I have two concerns; 1. The directions to the house were a bit confusing. To cut short, just go direct to the house from Hatsudai Station. The house use pin-type access. You do not need keys to enter the house. Just enter the pin and you are good. 2. All the bedrooms were on the top floor with quite a steep stair which I believe not suitable for elderly people.
Other than those, it was a great experience staying at Hikari’s and I will surely stay there again.
