I loved my stay- cute, clean & warm in the winter, it's exactly what I wanted to be able to get into Tokyo's active neighborhoods, but to be somewhere a little more quiet and private at the end of the night. The train is easy enough to figure out once you realize the branches are operated by different companies (keep a few yen on you to cover trips not on your three day card) & the three day subway card they recommended is the way to go. They were also very helpful with info ahead of time & are just around the corner of you need anything (their house has a sign similar to the one on your apt).
Again, clean, pleasant, friendly, not in the bumping center of crazy Tokyo, but as a visitor, I'm cool with training it into town so I can spend my money on eating great izakaya food, shopping for cool stationery and sipping beers in my quiet bungalow at the end of a long day of trekking.
