The place is located in a calm area close to Koenji Station, which means you can easily and fast get to central Tokyo.
The place is clean and perfectly sized for two people. Manami is a great host, very helpful and communication with her was fast and easy.
She helped us with getting tickets to Studio Ghibli Museum, which is also not too far away. She also lent us her pocket wifi, which is great for exploring Tokyo.
Highly recommended!
