This place is an apartment building, close to Tokyo Tower and with easy access to train and bus stations.
This well designed place has a modern touch and was enough for our family of 4 adults. We loved its Texas-size shower in a typical Japanese studio. Maybe the kitchenette would not be enough if you plan to use it to prepare your meals for your group, but it is very appropriate for a city-visiting family.
We booked 3 different Airbnb places in this trip to Japan, this one was the best of them all.
