Great modern home only steps away from the Mikawashima JR train station (Joban line), which brings you right to Tokyo Station in around 25 minutes. To go into areas like Shinjuku (40 minutes) or Shibuya (35 minutes), you'll need to take a single transfer (Yamanote Line at Nippori Station).
The home has all the modern appliances you can think of in a new Japanese home, such as air conditioner/heater combo units and a laundry washer/dryer combo unit, but the problem is that they are all in Japanese and do not have any translations. Some translations from the host (in at least English) would have been very helpful to better understand how to use these devices.
I was with a group of six, and we mostly all fit into the rooms with our luggage without much of an issue. The first room on the top floor was on the smaller side due to two single beds being put into the room and prevented the closet door from opening. I had to move my bed every time I wanted to access the closet, which is not ideal. Having only one toilet also provided a bit of a struggle to our larger group.
The host was terrific during my group's entire stay and got back to me very quickly on any questions or issues that we had. Very happy with his level of customer service, and I am very likely to stay in this Airbnb location again in the future with a large group.
