Hisao-san's place is near-perfect. Amazing sandwiches every morning, just about every amenity you could need, and a great location (about 10 minutes from Uguisudani and 15 from Nippori station). He even took me to the station when I checked out! A few things to note: His English is not the best, so you might have some difficulty communicating in person. However, he was very friendly and responded quickly to my messages. The water in the shower is often a bit too warm or cold. It's difficult to maintain a consistent temperature, but with a little effort you can do it. The pillow was tatami-style and a bit stiff for my liking. I nevertheless slept very well. Minimal noise from the neighbors! I would stay here again.
