Though it might be a small walk away from the nearest station, the residential area you walk through is very charming. On our way to the station every morning, we would drop by the fried food shop and senbei shop to grab a snack. The nearby Family Mart and 7-11 were also great for a riceball or too as well.
As others have stated, the home is near a train line, but all four of us didn't find the sound to be unreasonable. We slept through it perfectly fine. It'll be the only sound you'll need to worry about at night, as it's a quiet neighborhood too.
The location was also very easy to get to from Narita airport. Momo was also very prompt in responding to any questions we had. Overall, it was a wonderful stay!
