Good place to stay especially before your return flight in Narita. you can shopping for almost everything before you went back. theres donki nearby, shopping mall at the station and you could go to Narita airport directly from Koiwa station. on the way to the airport, dont forget to stop at Funabashi station for more option of shopping.

There was no cloth iron, the place could get a bit noisy with footsteps and people talking.

it’s good for those who wants to cook their own food
