The studio is perfect for one person. It had everything I needed to be able to prepare my breakfast (and other meals if I wanted to). The room was spotless and comfortable. Shower was hot, and there were extra blankets for keeping warm on a winter night. The location-only a couple minutes walk from Sengakuji station--is awesome, and I enjoyed exploring nearby Sengakuji Temple for the first time and eating my lunch on the temple grounds. Only downside to the studio was that there isn't much natural light, but that's not uncommon in Tokyo. I didn't meet Sally, but she always responded quickly to my questions.
