Tldr: Cynthia's house is so good, clean, cozy, the ambience is great (one of my dream house) and most of all she is very kind and patient.
She is so patient and responsive since a got in a problem when my booking suddenly canceled due to changing some settings in my profile, she's there until my problem was solved.
Overall the place is great, we have a great stay and all of my friends love her house. I'll book again to her house if I will travel to Tokyo again.
