Mitsuko's place is small but functional, ok for two people – the plan wasn't to stay in anyway! Hatagaya is a lively, nice area full of restaurants and cafés and the station is 5min away, which makes it relatively easy to get around Tokyo. Mitsuko replied to my messages quickly and sent us loads of helpful information on how to get to the flat. We arrived quite late and checked-in ourselves, everything was straightforward and easy. I'd definitely recommend staying at her place if you are planning to explore Tokyo for a few days.
