Generally a comfortable place, it keeps warm during the winter. There are ACs in every room. There were 3 bedrooms available (1 had 2 beds). You can tell it's an older house but it has the basics you need. They also prepared enough things for us 3 guests.
At first, they did not have a home router (so no home wifi), just the pocket wifi, me and my friends were a little disappointed by that. They supplied a pocket wifi but it had very low limits, so we had to rent our own. I contacted the host and they were able to set up a router, but only about a day before we left so that was a bit of a let down. But while they did it, they were very kind, which changed my impression of the host.
Pros:
1 stop away from Ikebukuro Station
A full place (bedrooms, kitchen, bathroom, etc)
Quiet neighborhood
Cons:
Older house, so bedrooms aren't sound proof. If you're a light sleeper, youll wake up from other guests.
3rd Floor
Not luxury/modern but decent
Works for a decent temporary stay in Ikebukuro
