Wow trust me when I say you wont regret staying at Risas. She will take care of you and her home is beautiful. Her two dogs are super friendly and never in your way.
The neighborhood is pristine and quiet but also has some nice places to eat out at if your not trying go to the Tokyo Jungle.
Transportation is easy as hell and super close. 200 yen will get you to Shinjuku or Shibuya in minutes.
Good Wi-fi at about 30Mps, access to washer and dryer and much more just read the description. Risa speaks english so no need to worry. Go for it!
