Katsuo's place is very clean & easy to get to. Instructions for check in is very simple.
The walk from JR Shinagawa station with heavy luggages & kids was longer than 10 minutes.
There is a long steep staircase we had to carry our luggages & kids up first which was abit scary and dangerous.
Inside set up is good for couple or adults but not for kids.
Tiny & neat but no where to put luggages.
Location for food is pretty good as doenstairs there is family mart and a few restaurants that is open quite late.
