Our stay at Ming’s place was pleasant. The description is accurate. It’s a small studio type apartment but it served our purpose. It’s 800 meters from Kameido Station and you can use your JR Pass on some lines which is handy. There are also two bus stops going opposite directions a stone’s throw away although we didn’t use them much.
700 meters from here near the station is Life at Kameido Clock, a supermarket open until midnight which is quite handy. Plenty of convenience stores around as well.
There are things that can be improved but overall we have no complaints. Good wi-fi, too. No comment on common working space nor laundry as we had no need for them but Ming is a responsive host and I’m sure he will respond promptly with any questions you might have!
