This hotel is located very close to 3 train stations making access to the whole of tokyo very easy. The quality of the rooms is exceptional as you would expect with a 5* japanese hotel.
The breakfast is quite good although very expensive for what it is.
WiFi and Internet is charged which is quite unbelievable for today.
There are many services supplied, you can get the bus direct to the airport from the hotel for 3000 yen.
Overall a nice stay but quite expensive.

This was my second stay at the Intercontinental Tokyo Bay, and although the hotel is still a good standard I do feel that overall the hotel standards are slipping.
My greatest concern would be the quality of the service in the restaurants. I feel both the service and quality of the food was not good enough either for Lunch (which I tried once and walked out) and Dinner which again was poor compared to other Intercontinental's I have used.
The rooms are beginning to look tired also, though impeccably clean as you would expect. The gym was constantly closed for "private sessions" though looking through the window it looked a good standard wish I could have got to use it.
For the cost of this hotel, which is not cheap by any standards I was left feeling disappointed, the first time ever in a Intercontinental Hotel.

I have just stayed here for 4 nights whilst on a business trip. My room had twin beds and was good size. There was also 2 sitting chairs and a work desk. Bathroom had seperate walk in shower and bath, and was very clean and well presented. It was probably the quietest hotel I have ever stopped in.
Good location, with a 10 minute walk to the monorail station, and Takeshiba station a stones throw away.
The only negative is the cost of drinks in the bar and restuarants - OUCH! You can however stock your mini-bar from the convenience stores that are on every street corner in Tokyo. The Narita Limosine bus stops at the hotel and costs 3000 yen. Haneda is 20 minutes via monorail.

I booked the hotel in Dec 2010 after our trip to Tokyo Disneyland. The hotel is conveniently located near the subway station (around 1 min walk) on the Yurikamome line. The Yurikamome line is very convenient to the futuristic Odaiba, and a very pleasent way to spend a day visiting Odaiba. The hotel is also very near (5 to 8 min walk) to the JR Hamamatsucho station.

Checkin was very quick and a IC Ambassador got me an upgrade to a room facing the rainbow bridge with sweeping views of Tokyo Bay. The room itself, like all Japan rooms were very clean, very nice bathroom but unlike most Japanese rooms were quite sizable and comfortable.

The area around the hotel has a 24 convenience store, some food joints along the road to the Hamamatsucho station. Altogether a very nice hotel made conveninent by the Hamamatsucho station closeby and certainly less expensive vs the rest of the ICs in the Tokyo area.
