I had already heard from a mutual friend that Sachie's home was exceptionally good value, but even then I was surprised by how pleasant a place to stay it was.
The apartment is located on a quiet street in a neighborhood with a good smattering of eateries nearby, a supermarket five minutes away, and only a 15min walk to Shinjuku. It is spacious and charmingly decorated, with lots of natural light, and a terrace that even has a small garden.
Sachie was unfailingly helpful and courteous, and explained everything with great care. She was full of advice about how to navigate Tokyo and make the best of the city. I will definitely stay at her place again next time I am in town.
