Both service and location is amazing. For both traveling and business trip, the location is top notch. For transportation, you get access to hibiya line, Ginza line, yurakucho, shinbashi station which pretty much goes to everywhere. Ginza is right next to it, which is famous for shopping and food. You will have no trouble accessing any place in Tokyo with these lines. For business, mainly it is held at either marunouchi or kasumigaseki(government) both locations are very close. If you want to walk around in nature. There is a big park right in front of the hotel. Very satisfied with the location. Service is great as well, they pretty much solve any problems or question I had.
