It is a spacious, quiet, and very conveniently located apartment. The Kikukawa station is only a few minutes away, and the Morishita station is also very close (a little farther away but still only several minutes). There is a supermarket right by the apartment (a few blocks away). We loved having two toilets and showers (it's rare to find an apartment with two showers in Japan)!
It was easy to talk with the hosts. They were very nice and helpful!
We have stayed in many apartments in Japan, but this is now our favorite!
