It's a well-located, small apartment close to the subway but VERY noisy. The train tracks are across the street. They provide earplugs for free, but I could still feel the trains. The apartment has a washing machine, and they provide laundry soap for free which is nice. The bathroom has a function to dry clothes. Keep in mind Japanese double beds are smaller than normal.
The apt was an excellent value for the price. It was clean, it has a washer and clothes hanger and the shower room has sauna and clothes drying capability. Tub was spacious and had auto settings. We stayed on the 5th floor and we never heard the train.
