Kota’s house is VERY convenient. It is only 10 minutes away from the JR Yamanote line. Good supermarket and restaurants nearby. Also fast easy convenience food. You can walk to Ueno Park which has many sites.
It represents a vintage Japanese home. There are modern conveniences like rice cooker, microwave, induction cooktop, washer/dryer, etc. but the structure and artifacts sprinkled throughout the house give it an authentic vintage vibe. Hot water pressure and bath was very good.
Sleeping on futons on the floor and eating off a low table while eating were a challenge for older (+64 years old) guests but Kota has two chairs in the house.
The other sleeping area is also the living room/dining room and quite small. Best for couples and small family to sleep in one room upstairs.
