Great house in Ikebukuro. Plenty of room for 6 adults—it was great having two toilets and two showers. Used the kitchen and washing machine—they work well. It was very convenient for us to be able to cook and do laundry since we were traveling for a while.
The house is about a 15 minute walk from Ikebukuro station, but that wasn't a problem for us. There is also a bus stop about 5 minutes away, which we used as well. There is a 7-11 less than 10 minutes away, and a Don Quixote about 5 minutes away—they have everything, and it's great for getting food you plan to cook.
The host met us when we checked in and showed us around the house and neighborhood, which was very helpful. She spoke Mandarin and a bit of Japanese, which we don't, but we got on fine with Google Translate—she's very nice. :)
The house is near a large elevated highway, which I noticed can be a little loud at night, but the actual the street the house is on is very quiet and nice.
