We loved our stay at Motoshi's.
His flat is very clean and new. It has everything you need during your trip. The place might seem a bit small but everything is well arranged, so it didn't bother us at all.
The location is perfect : 10 mins (on foot) from Ikebukuro station and in a quiet area.
Motoshi was also a great host, very kind a reactive.
If we come back to Tokyo, we won't hesitate to stay there again :-)
