Nice place, a short walk from Hamamatsucho Station and Daimon Station. Not sure about the route from Narita, but the route TO Narita is quite simple, a single line from Daimon Station, just make sure to get on a Narita Skyline line. The place is clean and comfy, not very spacious but cozy. The staff is nice and you can keep luggage before check in and after check out. They provide new pajamas every day and they're very comfy. Quite useful so you can pack a bit lighter. Our only small complaint was the slightly longer walk to stations, around 5-7 minutes. Not a big deal, still recommended.
