I stayed here for about 2 weeks.
There were a small kitchen, micro oven, refrigerator, kettle, hair dryer, air conditioner, TV, closet, restroom, shower, bathtub and Wifi.
It takes about 10 minutes to get this apartment from Uguisudani station.
The host's wife prepared us sandwich every morning for free.
Two washing machines were outside at the apartment. It cost 200 yen. They doesn't have a dryer function, but the room has a small veranda, so you could hang clothes out to dry.
It was very quiet around the apartment. and close to convenience stores, so you can buy something when you need it.
Uguisdani station is very good location, to Ikebukuro is about 15 minutes, to Shinjuku is 25 minutes.
You'll have a good time here, I recommend this hotel:)
