The room is very basic, but had everything we needed for our stay. There was several plug sockets to use, towels and a hairdryer were available. There was shampoo, conditioner and body wash in all the showers. The beds were surprisingly comfy. There was a basic wardrobe and a desk and chair in the room.
In the communal area, there was a microwave and a kettle to use. Both recycling and rubbish bins were available. There were indoor shoes available and separate shoes for use in the toilet. The showers always had hot water.
It had a self check in procedure, with the room door being open and the key left in the room. It was on the second floor, so a bit of a pain if you have a suitcase, but the owner was around when we left and he carried them downstairs for us. He also looked after our cases for a few hours after we had checked out.
This is above a Family Mart, which we used everyday for breakfast and sometimes for tea. It is close to both Okubo and Shin Okubo train stations with Shin Okubo being on the Yamanote Line.
I would highly recommend Lucky Hostel to anyone wanting to stay in Tokyo and if we were to go back, I would book here again.
