We had a great stay at Aileen’s place. The home was sparkling clean and Aileen was very responsive when we had questions. Location is good. It is about a 10 minute walk from Nakano station in a very peaceful, quaint neighborhood with many restaurants around. You are not “in the heart of it all” like you would be staying in Shibuya or Shinjuku, but it is a nice place to come back to if you are willing to travel a bit to the busier areas.
