Very hospitable and accomodating hosts! The bathrooms are clean and well maintained. It's somewhat near the train station, but a bit far from Narita Airport so you should reconsider when you have an early morning flight (you will not make it to a 7am-7:30am flight if taking train; Uber will cost 27k yen from the place to Narita)
The room is small with little room for movement or hanging out inside the room. we had 5 luggages and it was difficult to fix things among the luggages with so little space so you might consider asking for a large room.
