Manami's place was exactly how it was described on the post. Very close to Koenji station, two convenience stores right around the corner made things really easy to move around. The room is very well maintained and super clean, provided everything you need to make yourself feel at home. The only downside I can think of is that you don't get much sunshine during the day so the room gets pretty cold during winter. Shouldn't really matter though if you are exploring the town.
Communication with Manami was always quick and smooth. I'm happy to recommend you to consider this room if you are planning to visit Tokyo.
