This really might be 2 reviews as we stayed here on 2 separate occasions and had very different experiences, one great and one not great. On the good side, the hotel is very convenient to transportation and is easy to get to from Narita. Since it is near one of the main JR Shinkasen stations, it is a convenient hub for travel outside of Tokyo. The train station is also a hub for the many many rail lines in Tokyo. The hotel is beautiful and elegant with relatively spacious rooms (by Japanese standards). The bathroom is lovely. We booked a king bed and the first room in which we stayed was great. The staff was also very helpful. On our second visit, we checked in at 4 and were told we needed to wait for our room. When we got to the room, it was considerably smaller than our last room and the bed looked small. We went to the front desk and asked about it and were told that we had booked a king room, not a king bed, and that the beds in the king rooms could vary in width by 20 cm because of the outside dimensions of the building. I stay at Intercontinental properties a lot, and it would have been nice to have disclosed this information beforehand. I complained and we were moved to a larger room after a several hour wait (which impacted our evening plans quite a bit), but the staff were unhelpful and seemed very put out by our request. This was in such contrast to our first stay. This is an expensive hotel and I really don't like feeling unwelcome, which my family and I did. Furthermore, we were duly warned at booking that there was a 7000 yen surcharge for a second person in the room (my wife), and this might be common in Tokyo, but it is rather ridiculous to basically charge per person for a room where there is no significant material difference between having 1 or 2 people in a room (extra water)?

I live in Switzerland and Japan makes Switzerland look inexpensive! The Intercontinental is a nice, clean hotel with all that you would expect from a Japanese location. Comfortable bed in a smallish room. Great shower and bath and automatic toilets with heated seats and water spray.
I found the staff to be indifferent and although the food and beverage was good, they did try and turn us away one evening even though we were guests of the hotel. Prices for food and drink were beyond ridiculous which brought the rating of the hotel down.
The gym was small but equipped ok, I would guess it gets very crowded in the AM with only two treadmills, but when I went it was completely deserted.
The people of Japan seemed sad to me, lots of masks to stop colds, little smiling and after two weeks in Asia I found it to be the least friendly of my Asian stops.

Have stayed at the Strings at least 10 times. Always on business. Perfect location right on the Yamanote line with easy travel to Narita.

Great rooms and service. Very pricey compared to other options. If price no concern you would have a hard time doing better!

I stayed in the hotel with my mother recently. We were both presently surprised how lovely our stay was. Though situated above one of the busiest business hubs of Tokyo, once inside one is instantly at peace with the serene architecture, water walk way and open atrium.
The bartender impressed us with the martini recommendations of which there were 51 different martinis to choose from. The breakfast buffet was beautiful and our meal in China shadow has got to be one of the best Chinese courses I've yet to eat! Wow!
The hotel manager Colin McCandless greeted us upon check in and answered many of my mothers questions about Japan. He gave us his card in case we needed anything further. We felt very looked after throughout our stay and will happily book accommodation there again when next in Tokyo.
