We stayed 2 weeks and were feeling us like at home. Good and prompt communication. There a manned reception, the stuff friendly and responsive to our requests. We like it more if there is a person to whom you can talk.
The apartment was exactly as described abd showed in pictures. Very clean and very comfortable. Beds and pillows were comfy.
The area has huge options of groceries (tobylu, maruetsu, my basket), restaurants and shops. We likes indian restaurants. Due to relatively large indian community in Kasai, you've good options - highly recommended.
Small down-sides: no rice cooker; the stove ventilations upper levels were deactivated, only slowest level was working.
But still, overall 5 out of 5. We will choose the place again, when we stay in east Tokyo.
