I stayed 3 nights.
Things you might want to know if you choose a room with shared bath/toilet: the toilets are private (separate for men/women), the sinks are communal, in the hallway. The soaking tub & showers are communal (separate for men & women), bringing back memories of gym class. There are no private showers.
The location is great, an easy walk to the train station (or Y1,000 taxi); easy walking to the garden & castle, the food market, many restaurants, etc.
The hotel is very clean; the staff is helpful & friendly. I speak no Japanese, but we managed. The decor might be classified as depressing, but I chose to frame it as minimalist.
