Fantastic. Simply fantastic. Audrey's place is well maintained and the roommates are quiet. You can cook if you want to. There are many great restaurants in the Aoto area and various convenience stores are just 300-500 meters away.
The house is very close to the train station, and Keisei line goes directly to both Narita Airport, Asakusa, and Ueno... etc which are some big places you definitely want to visit during your stay in Japan.
In addition to that you may inquire about the Japanese lessons if you want to learn some Japanese during your stay. The Japanese teacher - Junna-san is a great teacher.
Lastly as someone who loves swimming a lot, I would like to mention that there is a pool about 20-min walk away.
Looking forward to seeing them again next time.
