This is a great apartment and a great host! I stayed in it for an extended stay (34 days), and so I became very familiar with all aspects of the place (the cooking appliances (a nice gas stove, rice cooker, hot water-maker for tea, microwave, toaster over, fridge), shower & tub, laundry machine, and so on). I loved how stocked the apartment was! There were boxes of tissues, plenty of toilet paper, tons of towels of various types, sheets, blankets, spare batteries for the TV remote, even ribbon and tape in case I needed to wrap any gifts. Basically there was everything I needed to live comfortably. The location is fantastic: 10 minute walk to Akihabara, 10 min walk to the Emperor's Palace park (great for jogging), 15 min walk to downtown Tokyo, and the Awajicho metro station is literally steps away, with easy transit to Ginza, Shibuya, Shinjuku, or anywhere you need to go, really. And the neighborhood is one of the safest in Tokyo. My Japanese friends who visited me all said that the apartment was so incredibly nice that I must be super-rich! But for a great Tokyo location (and the size!) I thought the price was very reasonable.
The host, Mayumi, is a delight. I met with her socially three times during my stay, and she was great fun to talk to and learn from about Tokyo. (Her English is great!)
There are some great restaurants very close to the apartment, including a well-known (and not very expensive) soba noodle shop and a "sweet sushi" (i.e., inari and things like kampyo rolls) shop. I ordered take-out from the latter four times, I think, and it was the best inari sushi I've ever had! There's also a Denny's and several Italian restaurants nearby if you just need something more Western. Really, it's a great place, and I'll rent it again if I have a chance.
One more thing: The view from the large wall-to-wall bedroom windows is wonderful! (And there are thick curtains to hide it when you need to.) The building is very quiet, although there are city street sounds (but those never bothered me).
