Excellent in terms of location (just across skytree), ameneties & cleanliness of the unit. We stayed as a family of 5 (2 adults, 2 kids & 1 baby) and only utilised the bed & sofa bed. A floor mattress was provided but we didnt use it as there really was no space to put it. I dont suggest more than 4 adults to stay here as it would be very crammed. Bathroom has low ceiling so may be uncomfortable if there's more than 4 adults. Mattress & pillows used were just ok. We had some issues to retrieve the keys during check in as it involved rotary combination locks but we were able to reach the host even at midnight at the time. This unit is within a building that is just for airbnb. Good base for Tokyo.
