I stayed at this place at the beginning of my trip, and for my last few days in Japan and it has all the amenities you need. There's even a kitchen with a stove and all the pots, pans, kitchen utensils, microwave, toaster oven, fridge, and freezer. Grocery stores and convenience stores are within walking distance which is great if you plan on saving some money by eating inside and making yourself a meal or even just heating up your food from the convenience store whenever you want becausw I know some airbnb's and hotels in Japan won't allow you to cook or heat up food inside the room.
He's so nice that he provides recommendations of places to eat and provides very easy to follow detailed instructions on how to find the airbnb and which train to take to get there.
I hope to stay here again the next time I'm in Tokyo.
