The hotel is directly opposite the number 7 exit of Akasaka Chiyoda-line metro station, or only 20m or so from the number 6 exit on the same side of the street, so it's convenient for transport. The area isn't a great tourist trap like Roppongi or Shinjuku, which is quite nice in my view, so it's a bit quieter than some places.
What you basically get for a moderate price is quite a small but very clean, modern double room with own bathroom. There is a restaurant downstairs. Given the area, most hotel staff will speak at least reasonable English. There is an OK breakfast which may be free depending on your room/rate plan. The beds are very comfortable, which is my No. 1 consideration!
A few doors away is a convenience store (called 'am/pm') which is OK for getting snacks, beer etc. Also, there are lots of restaurants nearby, and a Tully's coffee shop 5 minutes walk away.
All in all, a good place to stay in Tokyo at a reasonable price.
