About
Welcome to the share house.
This is a three-story apartment building with a live-in manager. The residential areas are on the 2nd and 3rd floors. Each room is a 1DK layout of about 13 square meters, equipped with a shower room, separate toilet, and a mini-kitchen.
The highlights here are the common spaces on the first floor and the rooftop. A kitchen space large enough for small cooking classes, complete with a shared large refrigerator. A laundry space and large public baths (separated by gender). A theater room in addition to the living room. BBQ facilities are available on the rooftop.
How will Guest spend their time here?
