First of all, cleanliness is not an issue at all here. As i had hoped from a Japanese hotel, everything was spotless. The stafg was very friendly, and spoke more than good enough English. The neighborhood is a bit quiet, but there are plenty of good food options around.
Its a bit of a walk to Akihabara, but not so long that I ever felt taking a train was necessary.
Obviously, compared to a standard American hotel, the room itself is small. However, unless you plan on exercising in your room, this will not be an issue, even for a tall (6' 3") person like me.
