The employee is responsive to answer for all difficulties that we had. We got an accident before we check in, and the girl employee (forgot the name), was helpful to communicate with the police for investigation.
The location is also great, less than 100 m from kuramae station (oedo line).
The room is fit properly for 5 people, since its in tokyo.
The price its also affordable for tokyo accomodation.
If you’re from haneda, there is direct access line, only 300 m walk to the hostel.
But the elevator is very small, maybe only enough for 2 people with luggage, and fortunately, not too many people stay so we don't have to wait too long.
The flush in the toilet was in problem too for several times, but after we sent a message, a few minutes the employee came to fix it.
So its very recommended to stay here for the group.
