Stayed at Kazuko's place for three weeks and it was great. The location is absolutely fabulous, about five min walk from the Shibuya Hachiko Exit, with a 7-11 convenience store on the ground floor of the building. Convenience stores in Japan are amazing. Portable wifi was fast and the air con / heater worked great. Kazoku was available via whatsapp the whole time and very responsive. Check in was a breeze, and she even left us some snacks on the table.

The apartment was small, but cozy and comfortable, with two single beds that could be pushed together. The tatami mat area was lovely. The "kitchen" and bathroom, like many Japanese studios, were quite tiny. The only thing to be aware of is that the building is half residential, half commercial, with some cafes, used clothing stores, and tattoo shops in the building as well. Also, the hallway lighting is quite dark at night.

Overall, the apartment had everything needed and the location was ideal. Definitely recommended.
