We stayed at Tony's with 4 Americans and 2 kiwis (me and my husband). We stayed in 2 rooms, joined by a hallway. It was a very tight space, but the price was good compared to other Tokyo stays. I would recommend 2 adults and 1 child per room, 3 adults felt a wee bit too cramped. Good thing we were close friends! Sharing a hallway also stunk a bit, there was a very cranky airbnb neighbor who got mad when we quietly came home around 10pm one night. Tony was a very good host, communicated very fast, allowed us to drop bags off early if needed, and check in was very easy. Id stay again with just me and my kiwi husband! The neighborhood was very adorable!
