Kota's place was warm and inviting. He had a personalized message waiting for me and an English guide for how to manage the apartment during my stay.
The apartment would sleep two easy enough, though you may feel a bit cramped. The living area and bathroom were cleaned well. You're walking distance (20 minutes) from Ikebukuro and if you want a night out in Shinjuku it's around a 40 minute walk. A 15 minute walk will get you to the nearest JR Line. The neighborhood was quiet and was a nice break from the crowds in Shibuya and Asakusa.
