Akane and Mitsu were very welcoming without being overwhelming and were very attentive - a very charming couple.
The traditional Japanese home is spacier than regular apartment units and cozy to even chill at home. It provides everything on the listing and beyond to ensure comfort, as if you were visiting a friend's home.
The neighborhood is a vibrant old Edo district, presenting a different side of Tokyo than your usual tourist traps. The Sumiyoshi subway stop is not too far, connecting to both the Toei and Hanzomon lines. Japan railway pass holders could take the hike to JR Kinshicho, I suppose.
Highly recommended for the culturally sensitive traveller.
