Akira/Jeff wasn't around when we stayed there but he ensured that either Michelle or Taku is there with us. He was constantly communicating and checking on us despite not being around which was useful in many situations (eg. we needed an iron and he got Michelle to retrieve it for us).
The apartment is very new and fully furnished. The only downside was the washing machine's spin dry function was not working but we could use the drying function of the bathroom.
Overall, it was a pleasant stay! The property was a short walk to shops, restaurants and public transport.
