Great stay!
Be prepared for small which is normal in Tokyo. Host was very responsive and made sure we got in without problems.
VERY CLEAR INSTRUCTIONS were given and very helpful for finding the apartment.
Lots of convenience stores nearby and close to a subway station. 20 min walk from Yoyogi park in you want the steps.
Separate heater in the restroom and small balcony for viewing and enjoying the weather.
Great place!!
