The place is fairly good! It's exactly as you see it, and actually for Japanese standards is not even that small.
The location is good enough that you can reach most places by subway or even walk, if you don't mind walking a couple of hours every day.
Everything was great! Lots of convenient places nearby and the surroundings are residential.
If I had only one constructive criticism to make the place even better, I would say the host should include more kitchen appliances, cutlery, cups, pots and pans, etc.
The kitchen was literally just the bare minimum, and it would be good to have more options to cook from home.
But overall, really good experience! :)
