This is a great spot for exploring Tokyo. You are about a 2 minutes walk from the Mita line that connects up to many of the other lines. You are also only a couple minutes walk from a convenience store and plenty of great restaurants.
The space itself was excellent, there is USB power on the wall. Air conditioning worked great even though I was there during a heat wave. Everything was clean and how I expected it to be. This is a property I would return to.
