This place is fantastic. There's a little cafe at the front door that is super cute and a Family Mark on the corner. It's very close to the Metro (stairs going down though) or a little more of a walk to the escalator on the Marunouchi line. We loved it. The electrical is upgraded from other apartments and that might matter to you if you are traveling and have "accessories" to plug in at night.
The free "WIFE" turned out to be a "WIFI" which was disappointing to us because that seemed like an adventure. ;) But, to be fair, a free wife would not have given us speeding internet access around the city. So... everything turned out just right.
