The location is awesome, space a bit on the tight side. We returned to Narita by using an elevator to the Asakusa station in the same block as the property, so that's really convenient. One doesn't need to go carrying bags too far.
I would advise the host to fix the bed as it was not really comfortable, specially for two people. I spent some night time fighting with the bed and trying to make it more comfortable. This lead to headaches for a couple of days.
