The place is very good and easy to find by map that Takeshi send to us very early before the day we check in.

10 mins walk from sumiyoshi station

7 eleven is next to hostel very good.

And sure he give me a door password too.

He welcome us with my name on blackboard at the entrance and a welcome card on our bed.

wifi is great. and have free cold and hot water to drink if you want.
Bathroom and Toilet good too hot water work good.

Bed is big and clean.
2 problem i have that
1. it's very cold in the room we go on december that temp is 5 degree outside i sleep next to window and Heater can't reach our bed it's warm only in front of the door.
2. Room very small and have limit space for 8 people in room the guest who came first put their luggage everywhere and dont have space for us.

If i come to tokyo next time maybe i come back here cause it's cheap & Clean and easy to reach anywhere in tokyo by train
