My family (three adults and one child aged 12) had the most wonderful stay at Keiko's place - a beautiful traditionally decorated Japanese house in Kita-Ku.
The house is surprisingly large - lots of space which we hadn't expected in Tokyo. We loved all the traditional aspects of the home - the tatami mats, the recessed seating and the lovely traditional decor. The beds were VERY comfortable - thick mattresses and warm bedding.
The location is brilliant - the local town street (literally around the corner) is so lovely, vibrant, with loads of excellent eating options. It doesn't feel overly touristy (unlike some other areas) and we feel like we had a very authentic stay.
The house is only five minutes walk to the station which was great with easy access to all the tourist spots.
Keiko is so lovely and helped us dress up in Japanese costume (there is a rack of clothes to try) and performed for us a traditional tea ceremony. We also availed ourselves of the origami paper and instructional books and origami'd up a storm! She was such an accommodating host.
Travelling in winter, the house was warm and the shower hot. No complaints whatsoever - we highly recommend Keiko's place and would say there again.
Thank you Keiko!
