My husband, 3 year old, and 11 month old stayed at Vivian's Airbnb. Pros: easy communication with Pinn via WhatsApp, tub, modern and stylish decor and amenities, large space for Tokyo standards and separate space for the kids. Things to consider: steep 4th floor walk up which was not trivial with two young kids, washer and dryer cycle is 4+ hours, small hotel sized fridge, and thin walls. Overall, was happy with our stay and will go the Airbnb route on our next Tokyo trip.
