The two bedroom (four twin bed) unit we rented was clean, cozy and well equipped. The surrounding neighborhood is quiet and mostly residential. Close to Kita-Kashiwa station which will get you to Ueno in about 40 min. Outside the station, you will conveniently find a Familymart and Hidakaya. The welcome snacks are a nice touch.
The room was small but big enough. Everything was clean. The staff were kind and helpful. The hotel was 2 minutes from Kashiwa Station and surrounded by bars, cafes, restaurants and shops, which made it incredibly convenient. I've stayed in Toyoko Inns in different parts of Japan over many years and always found them to be reliable, clean and good value.
