The house was lovely and gave you the sense of belonging to the city. Having lived in this city myself for some years, I know this is a good example of the form-follows-function Japanese architectural design, albeit this house can also say it has a handsome form too. Compact as it is, it has a lot of characters and warmth. The bathtub was the highlight. Location-wise it is in the middle of a nice neighborhood with convenient stores within 3-5min walk. Quiet, but it is by no mean far from areas where people go. Meguro (10-15min walk) leads you to Shibuya in 6min and the chaos of Shinjuku in 14min and is on Yamanote line. Shirokanedai takes you almost directly to either Haneda or Narita and is a good starting point for subway rides for attractions.

Above all, Kan-san and Shoko-san were lovely hosts. It seems they only normally take guests on weekends, but they really helped trying to arrange their schedule to accommodate me.

Very glad to have stayed : )

Bear in mind:
It does not have a TV, but plenty of books in the house will keep you occupied. And it does not have a microwave oven, but whatever store you buy bento from would do the heating job for you.
