You can believe each of the reviews for Mie as our experience was very similar. Mie contacts you to arrange a pickup at the airport bus depot for transport from Narita location when you arrive and provides it for your return to the airport as well. This alone was really helpful to us. In addition, the apartment is clean, quiet and efficient.
Togoshi neighborhood boasts a subway station in walking distance, a 7-Eleven for food stuffs, a fruit and vegetable vendor around the corner and the famous Togoshi Ginza shopping street at the bottom of the hill. (It includes a 100 Yen shop!) . There are plenty of restaurant and coffee shop choices nearby as well.
I agree the shower/tub area is tiny but it is very workable. Mie is very responsive and has a binder in the unit for local restaurants, etc. The washer came in handy since we were in Japan for several weeks and needed some clean clothes towards the end.
