We stayed with Kaori for two weeks and it was wonderful. The delicious breakfasts did not disappoint, and the apartment has great nearby amenities. It is very easy to get to central Tokyo from the nearby station, and Narimasu itself is definitely worth exploring if you want to see the quieter side of this city. We very much enjoyed our stay and Kaori is a very helpful and accommodating host. We would absolutely come back if we ever revisit Tokyo!
