Stay at Kimiko's place! Her place is very comfortable and clean. It is approximately 30 minutes away from Shinjuku and Tokyo Station (where you transfer from Narita airport.) Kimiko provides you with all the comforts of home. Her apartment is less than 5 minute walk from Hikawadai station. Along the way from the local station is Summit Supermarket and a Co-op market. Her apartment is a wonderful place to temporarily call "home." I would definitely stay again when I travel to Japan again.
