The Grand Arc Hanzomon was one of the hotels that I stayed in during my trip to Tokyo. The service from the concierge was very good. They checked us in quite quickly and were very helpful with all the questions we had about the rooms and all other things. The rooms were very nice and well maintained. Some of the other reviewers mentioned that the rooms were a bit small, but I thought they were pretty good, compared to the other hotel rooms I stayed in. Our room had an excellent view of the palace and of Tokyo Tower, and it was an excellent sight at night. The hotel is not that close to a lot of the attractions that Tokyo has to offer but the Imperial Palace is right by the hotel. It is also an excellent area to walk around and just enjoy the atmosphere of the district. Only thing is that if you take the subway to get to the hotel, the easiest route would be through Hanzomon station, which doesn't have any elevators so you have to carry the suitcases up several flights of stairs (at least we did!). Overall, it was a good hotel and a great place to stay while in Tokyo.
