Yoshi's place is convenient and easily accessible to many attractions in Tokyo area. there's also a 7-11 less than 30m away from the doorstep.
The nearest subway is always reachable by foot and easily connected to other various metro or JR lines.
There's also a lot of amenities available in the house which definitely made my family's stay much more comfortable.
The corridors in the house are surprisingly narrow, and the wash basins are small as well. At times the walkway will become wet with the splashing of water from the basins. Nothing too major as we could simply wipe them dry after using the basins. Perhaps having water absorbent mats at the basins will help. We would have preferred an additional shower room, but understood the space constraints.
Yoshi and his team were also incredibly accommodative, providing transport services from the Airport to BNB, from BNB to the train station, and even the Mt Fuji Excursion which we enjoyed very much.
Would recommend!
