We really enjoyed our stay at Naoko's place. It's simple but very well presented. The bed and pillows are comfortable and we really appreciated the umbrella's and the free wifi. It's a little bit of a walk to the nearest metro station but from there it's easy to get to Shibuya, Shinjuku etc We also found lots of little local restaurants serving excellent food! (and a ' Bondi' coffee shop that could do a 'flat white' - great for antipodeans.)
The place is run by a booking service so you won't get the face-to-face service but we found them to be helpful and prompt at replying to our emails.
