We had a great stay. The house was perfect for our mixed generation family of four with lots of bedroom space. Sangenjaya is a lovely family friendly neighbourhood.
There is a lovely pedestrian route (called the greenway) just one street in front of the house where you can walk for miles. Lots of lovely playgrounds, cafes, restaurants and shops plus the train station nearby is perfect.
So handy being only one stop away from Shibuya and we even walked back one day too which was easy. When we visit again we would definitely look to stay in sangenjaya again and this house if it were available! Koji is a great host too with quick and helpful replies to queries.
