Masami's place is super clean, cute, and cozy. We really enjoyed our stay. It held us four guest perfectly. Masami's has guides and instructions everywhere so there's never any confusion about anything. She also left us a cute little note and snacks. Highly recommend staying here, however the closest station is not accessible with a JR pass so you'd have to pay that 150 yen or something to use to Keio line to get to Hatagaya station -- but it was manageable.
