I travelled to Tokyo for a couple of time. Most of the time I stayed at a hotel in Shinjuku area. This time, I stayed at Mercure Hotel Ginza Tokyo in mid November 2012. This stay made me feel better than any time.
From Narita airport, I traveled using NEX train to Tokyo station and walked to the hotel. It was okey to do so and took about 20 mins to reach the hotel. The hotel receptionist was helpful. The check-in time was at 14:00 but we could kept a luggage(s) at the hotel with no problem.
The location of the hotel is very close to the main shopping street at Ginza area. Also one of the metro line is located at the hotel ground floor. Alternatively, we could walk through the main street, enjoy sight-seeing and reached at Ginza station within 10-15 mins. This was enjoyable. Nearby the hotel, a lot of Japanese restuarants, convenient stores and fastfood restuarant are located within 5 mins walking distance. This was impressed me.
The room size was standard compare to the same room rate hotels and typical for Tokyo area. The room was clean without any bad smell. Hotel's amenities were reasonable. Free coffee & tea were available in the room. An ice maker was located one on each floor.
Breakfast was in a standard range compare to other hotels at the same price range in Tokyo area. I could enjoy the breakfast with no complaint. For the same room rate, this hotel is recommended.
Overall, I would definitely come back and stay at this hotel again in the future. Ginza area is one of my best favourite area in Tokyo.

I stayed five nights at the Mercure Ginza. The hotel is located in the heart of Ginza and all the hustle and bustle of Ginza and shopping only a short stroll away. The area is also well covered with 24h corner shops which will provide you with all the essentials.

Check in was delayed as my room was not ready at midday. The deluxe room I had booked was large with a small seating area and a desk for working and a mini bar and tea/coffee facilities. The bathroom was clean and tidy and featured all the typical amenities. WiFi was free but service was slow and unreliable.

The hotel uses a very strange room deodoriser which is way too strong and takes quite some time getting used to.

Breakfast was decent and varied (western and japanese). Staff were friendly throughout.

As is typical at Mercure there was zero recognition for Le Club Accorhotels Platinum members, which is a shame and an opportunity missed.

Room rates are on the high side for Mercure.

Would I return? Yes

very modern, clean and polite staff.
there is a good french restaurant in there, dont, miss it.
it,s near to every were, easy acces to the metro.
the price is high, as every thing in Tokyo, we choose a good hotel to feel safe.
