I highly recommend staying at this airbnb especially if you need an apartment to quarantine at.
It's located in a pretty quiet neighborhood, about a 4-5 min walk from Heiwajima Station.
There's also a supermarket right next to the station to pick up some groceries.
If you need to cook, don't forget to buy some cooking oil and salt/pepper since it's not provided.
The apartment was very clean and the beds were comfortable to sleep on.
There is a retractable laundry line in the living room to air dry your washed clothes too.
Also, there's a TV that you can login to your Netflix, YouTube, and Disney+ account on.
