Kota is a wonderful host. His instruction booklet is a breeze to follow.
About 40 or so meters from the apartment is a 24- hour convenience store with the sweetest workers. Always ready to help and make suggestions.
Just note that if you use the F-Line subway, you will have to walk uphill a bit to reach it. There are other travel options available.
Other than that, my stay was fine. I recommend staying at Kota's.
