For the price point this is a great accommodation.
It wasn't entirely clear to us where to enter the building, but the host responded to our request almost instantly with an image that made it clear (follow the sign to the thai massage).
The room is just big enough for storing two suitcases. You can open one of them, but then all of the space will be taken unless you put them on the bed. There is also a small refrigerator in the room. Unless you are travelling with minimal luggage I would definitely recommend getting this room over the smaller ones available in the same complex. Some guests in the smaller rooms had to keep their suitcases outside their doors (making the already tight hallways even harder to navigate).
There are two showers wich were clean and seemed to suffice for the number of people staying as there was never more than one person waiting to use them. The same goes for the toilets which are one Japanese squat toilet and two western ones on the other two floors. The latter are tightly layed out but it's manageable. Don't expect fancy seat heating though ;)
The kitchen unfortunatley looked quite messy several times. It did get cleaned regularly which helped and of course this is mainly a matter of how the other guests treat it and not really the hosts fault. Still we never really felt like cooking there and rather got food elsewhere. During our stay we saw several improvements happening already for example in how the trash was collected and I expected since this is a relatively new Airbnb things will turn better in the future.
Generally be aware that there are many people staying here in a pretty confined space. Don't expect to get any sleep unless you have ear plugs, since there is always someone snoring or taking a shower at midnight. This was totally expected and is not meant as a critique.
There is nothing notable for the typical tourist in the neighbourhood, in fact it's a red light district, so expect some noise from people on the street at night. However, it feels absolutely safe. JR Kinshicho station is just around the corner and will get you everywhere fast. Skytree is in almost walking distance (30 minutes) or a few stops by a nearby subway.
Would stay again if on a tight budget, otherwise I would likely invest in something slightly larger.
