Manami is an excellent host with a clean, well located apartment. She's very good with directions and communicating. Koenji has a lot going on in terms of shops, music venues and night markets. For something mellow, there are nice quiet streets to walk along including a canal that people jog along situation north of the subway tracks between Koenji and Nakano stations. With my athletic days behind me, climbing into the loft to sleep was not an issue. Perfect for solo or couple travellers.
