Clean compact place. Very close to train station. Couple of stops to get into Subway Metro network. Direct trains to Narita airport. Lots of amenities around. If you have lots of luggage you might be bit tight on space. Host also provided pocket wifi in addition to normal wifi, which came in very handy. Kitchen had enough utensils. The bins are bit small, so if you are staying long it could fill up. Just let the host know he will quickly sort it out. Don't leave the filled bin bag outside in private area. We made that mistake and the bin bag was ripped up by (I think) cat!
In general very handy place. We stayed there for 3 weeks and thoroughly enjoyed our stay.
