As promised, Haruko came to pick me up at the local station despite my last-minute booking. She is the sweetest woman who made me dinner the same evening and breakfast the next morning. She is the sweetest lady and was great to my boyfriend and I. The bathtub was wonderful and everything was so clean.
The location is nice, though it can be a bit stressful always thinking about catching the last train. However, a taxi from Shibuya is 3000 yen so it won't bankrupt you. All in all, an awesome alternative to hostels and hotels and a luxurious private accommadation in Tokyo.
