Kaneko's place was absolutely amazing! One of the cleanest places I've ever stayed in, if not the cleanest. The location is wonderful, it's a little in the residential area of Ikebukuro but a quick walk to the station. I'm a heavy sleeper so this isn't an issue, but if you're a light sleeper, there are train tracks right underneath the balcony (the balcony is great!)/next to the building. So you do tend to hear trains coming to and fro. It's also great to just look at and enjoy, so there's the pros and cons of that!
Overall, Kaneko's place was wonderful and I would love to stay again!
