We stayed at Suyeon's place for a few nights and really enjoyed our time. We were 2 couples with 2 infant children and suited us well — really clean and organised with everything you need.
The quiet neighbourhood was nice, but also had quick and easy access to Shibuya and other areas when needed. Suyeon was very helpful and had great suggestions for the area.
I would definitely recommend staying here and hopefully we can make it back someday.
