I can't recommend this place highly enough. For a single traveller it was perfect - the bed was comfortable, the air conditioning worked great, the private shower had good pressure and got hot quickly. I didn't use the kitchen, but if you want to make your own food that is available too.
The place is a short (5 min) walk from a metro station that will take you straight into the city (30 mins to Tsukiji/Ginza), and there are a few restaurants and convenience stores nearby. There is also a park nearby that has a scenic running path along along a river. The neighborhood is quiet and I slept great both nights.
Finally, these are the best AirBnB hosts I've had. They are friendly, answered all my questions, and had helpful suggestions. I also needed some minor first aid help during my stay and they cared for me without hesitation.
I will definitely be looking to see if this place is available next time I'm in Tokyo. You should book without hesitation if this place is open.
