The place was small for two people but still worked absolutely fine. It was sparkling clean indeed, felt very fresh and had everything you needed. Instead of taking the subway one station we had a 20 min morning walk to Ikebukuro stn., where you got to see the neighborhood nearby the apartment as well as parts of Ikebukuro on your way in.
M was also a very nice host, super friendly and informative with his messages and very quick responses, and he also gave several helpful tips during our stay!
