Nice, quiet location to explore Ikebukuro. A 15-20 mins walk from Ikebukuro Station. You will pass by many eateries and supermarket on the way.
The house would fit 3 persons comfortably if you have large luggages. Do note you will need to climb one floor up the stairs.
Naoto-san also responded quickly to any queries we had. All necessary amenities were provided, plus some tasty snacks! Bedroom was also warm during winter.
Overall we had a great stay for a week at Naoto's place.
