Great location, close to Narimasu station and large supermarket (Walmart).
We certainly know what we signed up for, but I think this was more than we hoped for in a negative way. We have stayed at many places in Japan, most of the places are as old if not older than this place. I think this particular unit has great value (cost), but the unit itself was not very comfortable for us. The bathroom situation was probably the most bothersome, as the toilet and shower/tub is all in one room. So after you shower, the entire bathroom is wet. The bathroom could use some cleaning and drain needed to be cleared out. While we were there, we had some visitors, namely cockroaches and something that bit me about 10 times while we stayed there (never saw it though).
Overall, the place needed a cleaning.
