The location is close to Keikyuu-Kamata Station. The room is very clean and spacious. The toilet is pristine and clean, and the toilet seat is warm. One sofa bed and a futon, both comfortable. You can use the washing machine or the laundromat outside if you have more to wash and dry. Our room is at the ground floor which is very convenient. It's next to the train track but we can barely hear the noise. The only downside was heating; the toilet and futon space can feel bit cold in the winter.
I would definitely recommend this room to others.
