I was about to say the same about the subway-station, stay left and you will find the closest station.
I stayed at ANA IC two weeks ago and I LOVED the hotel, although it is not that central. However I had stayed at Conrad for 4 days before ANA, so I was kind of finished with Ginza and that district. The club-lounge at ANA IC is VERY good and big. I also got a very nice upgrade, as an Ambassador, a suite.
