This listing is pretty accurate to what is described. The hosts were responsive and friendly. The shared facilities were cleaned everyday.
The location is great and it is walking distance to the Toei Asakusa line which connects you directly to Haneda Airport, and the Ginza line which connects you to major stations. It is also a nice walk to Tokyo Skytree. There is a shiopan bakery (pain･maison) on the way to Skytree and I highly recommend it!
There are some small basic things you would need to buy on your own like a tissue box, drinking water, detergent, etc. but otherwise, everything else is provided.
The internet was fast and the connection was great; I was able to work from home while I was here.
As it is a sharehouse, you should basically use your room with that fact in mind for the respect of the other guests in the building (thin walls, using shared spaces, times, etc.). If you are able to respect other people and have an open mind, you should be alright with staying here
