Stayed here a couple of times now whilst on business trips to Tokyo. The Hotel Metropolitan Marunouchi is in an ideal spot for exploring Tokyo being just a few steps from the Nihonbashi exit of the vast Tokyo central station complex. Very handy for trains to and from the airport, the Tokyo Metro and Shinkansen lines.
Rooms are spotlessly clean, although a little small (but typical of Tokyo hotels). Staff are friendly and helpful and breakfast is fairly good.
Apart from breakfast I've not eaten at the hotel resturant as it seems a little pricey for dinner. Good Japanese and Western-style food can be found amongst the multitude of restaurants within the Tokyo station and shopping complex next door.

The location of the Hotel Metropolitan Marunouch was excellent. [Take the Narita Express to JR Tokyo Station, get off at the JR Tokyo Station and go up to the first floor [the train comes in on B5F] and go out from Yaesu North ticket gate and exit from the Nihonbashi exit. The hotel [Sapia Tower] was right across the walkway.] Check-in is on the 27th floor; so you are guaranteed a great view since the rooms are above the 27th floor. The rooms were small by western standards but not bad, very clean and excellent views of the city. We opted for the breakfast add-on; 95% japanese breakfast which I enjoyed. The concierge was very helpful, in getting us a 1/2 day tour on New Year's Eve with Hato buses. Thoroughly enjoyed the tour of the Tokyo Tower, Imperial Palace Plaza, Asakusa Kannon Temple and Ginza. Not many places were open during the New Years [we were there from December 30th - January 2nd] but was able to do some shopping. Had some wonderful meals at a very reasonable price at the train station. It is a city in iself. New Years Day the hotel had a rice making [mochi] demonstration that was very entertaining and on January 2nd, they took us over to the Imperial Palace to see the Emperor and Empress and family. The palace gates are open only twice a year; the Emperor's birthday and January 2nd. We also bought a one day pass for about $10 per person and rode the green loop, Yamanote line that took us to Harajuku, Meiji Shrine, Ryogoku where the Sumo stadium and stables were, Ginza where the designer shops are; the most expensive real estate in Tokyo and back to Tokyo Station. The hotel is walking distance to Ginza and the Imperial Palace. When we return to Tokyo to see the fish market and sumo we will definitely stay at this hotel again. It was perfect.

We chose the hotel because of the location for two days in Tokyo, after returing from a longer trip in Okinawa. Very clean modern business hotel with usual, very good japanese service. The rooms are small (as with most hotels of similar category in Tokyo), so better go for the larger rooms at a modest price increase.

We'd certainly come back, very good price/value, considering the central location with virtually direct access to Tokyo Station and the close Marunouchi shopping district.

So easy to get here from Narita. Front desk helped us adjust our reservations which were complicated due to changing business plans. Lovely room with great views of the city. Make sure you specify non-smoking room. Most hotels in Japan have not made the jump to all non-smoking. I was put in a smoking room but could not tell at all and I am super sensitive to it, so they did a great job. Breakfast included and buffet had both European and traditional Japanese foods. Had to have the front desk forward faxes to another hotel in Utsunomyia after we left and this was handeled swiftly. Excellent customer service. Will use this as my base hotel for business trips to Japan.
