As you certainly already read, Hisao-san is such a nice host. Every morning his wife prepare a sandwitch in a plastic bag and put it to our door, Hisao-san woke up at 5:40am to bring me to the Nippori station for my train to the airport.
Great price, i don't think you can find a better place in tokyo with such value for your money.
It's located near Uguisudani station, around 10 minutes on foot from the North exit. Very quiet.
I'm sure to go back there on my next trip to Tokyo !
