We stayed at Chisaki’s house for our quarantine. It’s an easy access with the train and everything is close by. She was very fast in her responses whenever I had questions and she was very accommodating.
A little note for those who drive to her house is that it is located in a typical Tokyo neighborhood so that means a very narrow road. The car we rented was huge (not our choice) and had a very hard time turning. So I suggest arriving by train or park somewhere on the main road and walk 1min to get to the house.
Other than that, it offered us a refuge to our stressful return to Japan during pandemic and it was perfect.
