Check-in and check-out were really easy.
The area is very quite and you can reach many places easily by foot (e.g. Akihabara, supermarkets, metro station).
The room was clean, the bathroom is rather small so if you're over 180cm tall it might be too small for you (but i guess that's normal in Japan because the bathroom im every other accommodation I lived at was very narrow so far).
It was very cold in the room (outside temperature was around 0-10C during my stay), fortunately the air conditioner had a heating option with a max. temperature of 32C.
There was enough toiletpaper , shampoo, conditioner, towels, even toothbrushes were there for us to use in case we didn't bring any. Overall I think it was a good place to stay at in Tokyo!
