Nana and Yuta are some of the most kind and hospitable people you'll ever meet. They were very helpful during my stay, always ready to lend a hand or just idle conversation during my downtime. Anna is also such a sweetie and never fails to brighten everyone's day when she comes out to play! The actual place is also very well kept, comfortable (the kotatsu is essentially a black hole during the winter time) conveniently located.
Between the wonderful company I had and the cozy environment Nana and Yuta provided, coming to stay at Sato's san's Rest was probably one of the highlights of my vacation. I would definitely reccomend Sato san's Rest for anyone traveling to Tokyo.
