A great place to stay, either short or long term.
I stayed here when my flight was constantly being cancelled due to the Covid-19 restrictions and wound up staying for over a month in total. I couldn't have asked for a better place or location.
The amenities in the apartment are great. You have them all. In addition, you have regular WiFi (or you can go wired if you want) which is stable with good connectivity. There is also pocket WiFi for when you are out and about.
Local shops are great and inexpensive for shopping so you can eat at home, but there are a good variety of local restaurants nearby, too.
The apartment is in a safe area. I found it quiet compared to other parts of Tokyo and was comfortable to live in. It's not far from the subway line at all and that gives you quick access to the popular parts of Tokyo.
A great place to stay, affordable, and a fantastic host. Highly recommended.
