Two friends and I stayed at Satsuki's apartment for 4 nights. It is exactly as shown in the pics: spacious, clean and cozy, providing all you need for a comfortable stay in Tokyo.
As some reviewers mentioned, the JR train (one line goes directly to Narita airport) runs right behind the building, but you get used to it. The Kinshicho subway station is also close by, from where you can start off with discovering Tokyo. Some grocery stores, bars and restaurants are all in walking distance.
Satsuki is a very kind and helpful host. He was very responsive and even provided us a nice welcome gift.
I can only recommend Satsuki's place.
