In mid Jan 2013 we stayed at Grand Fresa Hotel in Akasaka Tokyo.
We were there for 6 days and had a standard double room plus a triple room for our three children. As you would expect of Japanese hotels, the rooms are small by western standards but as long as you keep your stuff tidy they are plenty big enough. The rooms we had were western style and the beds were very comfortable. My 18 year old son found the bed a bit short for him but he is 6 feet tall. Bathrooms were small but practical and everything is very clean.
The rooms appeared to be very quite but too our surprise the whole city was incredibly quite anyway so the rooms don't need any special sound proofing. There are only 3 rooms on each floor of the second building where we were (and we had 2 of them)) so noise from other guests was also not a problem.
The location is great for restaurants. There are more than you could possible need and all in walking distance. If this is your first time in Japan there is an all chicken restaurant across the road called "Yaki Tori" that is a great introduction to the Japanese restaurant routine with one staff member who speaks excellent English and is happy to explain how everything is done.
The hotel's breakfast options looked to be over priced compared to local offerings outside so we didn't use the hotel option for breakfast.
The hotel is almost on top of the C06 subway station so transport is easy. Although you do need to change lines a few times to get to some of the popular tourist sites.
We used Bookings.com to book our rooms and it seemed good value to us although this was our first time in Tokyo so we don't have much to compare it to.
Overall we were very happy with our experience at Grand Fresa Hotel Akasaka.
