Location was good once we found it. We found the directions ambiguous and the "Getting there" link to G maps will take you to a different place entirely unless you delete everything after the first numbers. If getting train from Ueno, get Ginza line (underground) and get off at Tawaramachi, not Asakusa. Then it is only a few minutes walk. Interesting neighbourhood. Once you find the right street, the door is between a florist and a pizzeria.
Host was responsive and flexible with check in and check out.
The facilities are generally good, though we personally disliked the hard bed and buckwheat filled pillows, which were crunchy! There is no sitting area. For dining in, there is a small foldout table and stools. Bathroom was good (be patient to get hot water) and there is a washing machine/dryer but no instructions in English. G translate was no help for this.
