Yume's place is a private apartment. The nearest JR station is Takadanobaba station, about 2k from the house. We struggled a bit with finding the house when the GPS took us to an animal hospital/clinic, but Yume helped directing us to the house which is just at the back of the clinic: go back towards the bridge and take the road along the river before branching. The house is clean and clever design of the space. The neighbourhood is quiet but accessible to restaurants (the road outside Takadanobaba station is full of them) and other shops. Yume is a great host and always responsible. We will come back if we are visiting Tokyo again in future.
