Kazumi's place was fantastic! About a 10 minute walk from the Marunouchi Line which is the main one I used to get around the city. Very close to Shinjuku Station but not too close to the hectic-ness of that area (tucked in a nice residential area). It was spacious and clean and perfect for two people! The laundry machine was a definite plus too. We were allowed to drop off our bags before check in as well. Highly recommend this place for a Tokyo stay!
