We stayed in Manami's apartment for 5 days. Although we did not meet Manami she was super fast with all communication and provided detailed instructions for getting to the apartment. The apartment is located in a quiet street about 5minutes walk from the centre of Koenji and from the train station. This is an awesome place to stay if you want a breather from the craziness and neon of Shinjuku etc, its a bit more relaxed, has great vintage shopping and restaurants and bars. Manami's place was impeccably clean and neat for our arrival. A washing machine is provided which is great. The apartment is compact, and the sleeping loft has a low ceiling so consider this if you get claustrophobic, it can be tricky to get up there if you are very tall. But the futons are very comfortable and its a perfect place for a couple. Recommend staying here.
