Zooey's instruction is spot on and the check-in process cannot be simpler. The well-equipped apartment is centrally located and in a very safe neighbourhood, it is near the US Embassy. The closest subway station is roughly 5-10 minutes away, and the elevator to get to ground level is very helpful for tourists with their luggages. It is a "mega" station because it intersect with 4 different subway lines on the Tokyo Metro network, and it is a snap to go to any of the sightseeing location - just a short hop to get to Dome City too where I attended TWICE's 1st Dome Tour!!! Being centrally located makes the ride fairly cheap too, usually 165 yen one way. Depending on where you entered the station, some lines are closer while others may be a 5-10 minutes walk away, but you can manage all that inside the station. There are two Starbucks I went to (one inside the station, another one is across the street, just Google map it) with plenty of convenience stores around, and staff usually speak English as well. There are also a lot of restaurants around, I have had fluffy pancakes at Bubby's across the street, Chashu Ramen and Curry Katsu on Rice outside the station, good quality food at lower prices than I have to pay in Canada, so in essence, I actually saved money on food during this trip to Japan. All in all, a wonderful stay.
