If you do your research, you will find that the Sunroute chain hotels are a business hotel. In Tokyo, this means small but clean rooms, good service, and few frills. I have stayed at two Sunroute hotels, the Takadanobaba location that I am reviewing now, and one in Nagoya. Both of my stays were excellent. This time, I was traveling with my fiance. Our room barely had enough space for our luggage and the two of us, but we knew this ahead of time and it was not a problem. The room was clean and comfortable when we weren't jumping over our luggage to get from one side of the room to the other.
The location of the hotel is excellent, it is literally across the street (and a small street at that) from both the rail station and the "Big Box." Big Box is a very large, very square building that is a shopping center of sorts. It has a Uniqlo (kind of a Japanese Gap), some restaurants, an arcade, bowling, and various other shops. The surrounding streets of the Takadanobaba area have plenty more to offer in terms of shops and restaurants. The next station down from Takadanobaba is Waseda, which is the location of a prominent Japanese university. So the surrounding areas (including Takadanobaba) have plenty of (mostly) reasonably priced shops and restaurants.
Overall, I highly recommend this hotel for it's location, neighborhood, cleanliness, and professional service (some of the staff will speak English, though others may not). If you are not traveling alone, keep in mind that the rooms are quite small for more than one person. On the positive side, many Japanese hotels charge an extra fee for a second person, this hotel did not.
