This hotel is old and currently under renewing. The whole building was covered and nothing can see out of the room's window. This hotel is located at about 7 mins walk from the Akasaka station. It is also at a walkable distance to Roppongi station. These two stations have different Metro lines and we usually walk to Roppongi for food, shopping, commuting etc.
There's no WiFi and only wired lan provided, don't forget to bring a router to enjoy the high speed internet.
