Location
Hikarigaoka is a bit far from the places you'd want to explore as a tourist, and the house itself is a bit of a walk from the nearest station (Hikarigaoka). Once you get used to it, it's isn't that bad. Besides, we went in spring, and the weather was perfect to go on long walks. There is also a bus stop within 3 minutes of the house on foot that can get you to another station (Narimasu / Chikatetsu Narimasu) that has multiple lines connecting to Ikebukuro, so you can try exploring that option as well. There is a pretty big 7-Eleven within 2 minutes on foot, which also offers baggage delivery services to the airport.
Communication
The hosts don't speak English, but that much is obvious from the Airbnb description. They speak Japanese and Mandarin. I can speak / understand a little of both, so I did just fine. My friends were fluent in both, so that was even better. Despite the limitations of my Japanese and Mandarin, the hosts were very kind and helped me a lot. I lost my wallet on my first day and they helped me retrieve it from the 7-Eleven where I left it at.
The Room / House
There is nothing to complain about, really! The room is more spacious than any other you can find in Tokyo for the same price. There is an actual closet, a small desk I used as a vanity, and lots of floor place for you to keep your luggage. The house is always sparkling clean, and they have everything you need-- you can ask to use the refrigerator or microwave if you need them. There is shampoo, conditioner, and body wash provided. The Wi-Fi is decent. And there is a dog, who is very friendly and cute. There is also no curfew, so you can go back any time as long as you advise the hosts via Airbnb message. And everything is clean, like seriously, I was not able to see even a speck of dust in the house during my whole stay.
All in all, I would definitely stay here again, but not in the summer when the walk to the station would be torture. Any other season would be fine. You should book this if you don't mind taking an extra 20 minutes going downtown and if cleanliness and having a big space is important to you.
