Apart from the noise (which we were already aware of via the other reviews, there was only one problem: dust. It seemed as if it had been cleaned months ago and no one came to check it before we arrived- the dust was at least a few weeks old (either that or the cleaners just didn't do a very thorough job.) Despite this the rest of our experience in this airbnb was incredible and we really enjoyed it. The 2 beds in the living room/kitchen don't have a proper wall or door so just be aware of that.
The area is amazing, one stop from Ikebukuro and the station is basically a minute away by foot.
I would stay here again if there was less dust!
