Isao and Saori's nice appartment is located close to Kami-Itabashi station (7mn on foot) thus it is very convenient to reach quickly Ikebukuro station and also very calm and relaxing. I met only Isao which was very kind even though I made a mistake with my flight time arrival. The place is quite big, you have everything you need in the flat to cook etc In case you have a question or need something, they live at the next door! I recommend it!
