Nice place for a short a break. We were a family with 2 kids ( 9 and 4) and we found the place to be comfortable, even thought at first we thought it was going to be a bit tight.
We did have a 4 pieces of large luggage, but if you are out the whole whole day and plan the luggage placement, it could be manageable.
Plus, the host was super helpful in helping with the luggage as its a walk-up and placing it in the store area.
The location was in a residential space and we loved that we could go to Roppongi / Omoto Sande on foot, and there were 2 lines accessible in 10 mins walking distance. There are some nice vegan places in the area too.
The smart TV was super helpful to have for the kids, and the biggest draw for us was the bed set up in the master where we could have the younger (4yo) and (9yo) int he same room and allow for co-sleeping, and then duck away into the other room which has a queen.
The thin walls / floors I read about in earlier reviews werent an issue for us.
