Yuki and Emuri's home is beautiful. You can't fault it. The home is an amazing century-old traditional house in the back streets of Hiro-o near Shibuya, but it's completely renovated. The downstairs consists of a bedroom, bathroom, and luggage storage room, and upstairs consists of an open-plan living and kitchen area with balcony. The only thing worth mentioning (but we were warned) is that the main bed is only a 'semi-double' so it's quite a squeeze for two tall adults. That said, there is a futon couch upstairs that could be used if desperate.
Hiro-o is a lovely neighborhood. It is quite hip, and filled with great cafes, restaurants, and boutique shops. Hiro-o station is a 2 min walk from the house, so very convenient.
We only meet Emuri, but what a gem she is! She met us promptly at 2pm at the Starbucks nearby, and we walked to the house together. She also helped us by making dinner reservations for us.
Overall, this was our favourite accommodation in Japan, and i thoroughly recommend it to couples.
