Cute baby rooms on the 2nd Floor of the La Fuente building in Daikanyama, just across the road from the Dixsept building. There are only two nursing rooms in a very confined space, so difficult to take your pram in with you, but the rooms have a locked door and cute wall prints.

My rating – 5/10 (Too tiny. I would actually downgrade this to 4/10. It could have been a higher rating if the nursing rooms were large enough to fit in the pram)
