Very easy communication: Mieko lives just next door so you can easily solve any questions any time.
In terms of hospitality I was feeling like on vacation in my grandma's place. I think Mieko is the most welcoming host I ever met (I use airbnb really often).
The place itself is very well organized. A lot of tiny things prepared for you everywhere like separate towel in any place you might need it, water and refreshing drinks waiting in the fridge and so on. Sparkling clean and have everything for long term stay.
Place itself well suitable for work from laptop: there is normal table, good WiFi and no noise from the street.
Location is great: two minutes from everything: hatagaya station, coin laundry and bakery.
Great value for its price. Recommend to everyone.
