Stayed here as a group of 3 for 10 days. The listing is fairly accurate, comes with a good amount of amenities; Towels, utensils, soap, conditioner, body wash, blow dryers etc. It is a little smaller than it seems in the pictures, you may find it a little cramped in a large group but with three people the space was enough for us to still be comfortable. Check-in is straight forward as the host provides detailed instruction on how to get from the airport to the station, and from station to the apartment.
7/11 and the train station are both 5 min away, and a grocery store is near the station as well. There are other stores and restaurants a 15 min walk into the city including other grocery stores with a pharmacy if you need one. Its very easy to access the rest of Tokyo direct from the station, we had no trouble getting around. Pocket WiFi available is reasonably good as well.
Only thing of note is that the walls are thin, and in the mornings there is a good chance you will hear the neighbours but it isn't really that big of an issue for the most part.
Overall a good and enjoyable experience, I would definitely stay here again.
