All are good, place is quiet, clean and all electrical items function well.
Location is convenient with 15 minutes walk to the different train stations (JR & Fukutoshin line).
The only thing that bothered us was the stair from main entrance to the unit, it is very narrow, to move with big and heavy luggage is a struggle and can be dangerous, having said that it's happened only during the first day check-in and the last day check-out.
Overall we are very pleased with the stay at Ichiko's place!
