Great place to stay
Spacious, clean and worth to value. Subway stations (Iriya station or Inaricho Station) are in a walking distance and if you’re lazy to walk, just take taxi, easy and not expensive. There’s a big supermarket near Iriya station where you can buy eating stuffs and fresh fruits and vegetables to cook at Kentaro’s place.
I would say Kentaro’s place is a nice and roomy place to stay in Tokyo.
