We loved staying in Koenji, it was a super cool area with great bars and izakayas. The apartment is in a great spot and, while it's quite small, had everything we needed for a short stay. Aiho (Choco's helper) was the nicest, she visited to give us welcome donuts and treats! So lovely. It was a bit hard to contact Choco to get directions to the flat, but they were very clear once I received them.
