Kenji's place is well located, very close to Ikebukuro station and many great restaurants and shops.
The room itself is quite spacious. We found the beds to be a bit stiff for our taste though so be aware of that.
We had a small issue with having no hot water for a day, but Kenji was very quick to respond and rectify the issue, also issuing us a small refund for the inconvenience, which was very considerate.
