Daisuke's apartment is very comfortable, 5 minutes walk from Keiyu Kamata metro station (approximately 500 meters, please note that this is not the JR metro, for JR pass or metro pass users you have to pay).
in front of the apartment there is a laundry and 7 eleven minimarket, very convenient for your needs. in the apartment there is 1 queen size bedroom and 1 sofa bed, and also there is kitchen with full utensils, suitable for those who like to cook.
I really loved the small bathroom and separate small toilet, for Asians like us it's still comfortable, but if used by westerners it might be a little uncomfortable because it's too small. But for all I really recommend this apartment. definitely will come back. Thanks Daisuke san & Akane san
