Serina is a lovely host. We spent many evenings together, where she went out of her way to show me around Tokyo. Her home is cosy, the bed is super comfy, and a hot coffee was always waiting for me in the morning. The train stations are close by, 5 minutes walk and 5 minutes ride depending where you're going. She lender me her bike for the week. I did not want to leave! Her English is perfect which makes everything super easy, as she'll be happy to give you directions. I consider her a good friend in such a short time and I'll be sure to visit again.
