First of all I want to say that Yuichi was extremely helpful and very responsive. He was very nice and will respond within an hour of me messaging him. The location of his home was very close to the station (within 5 mins walk) and very close to a big supermarket (located next to the station). The neighbourhood was very quiet and lots of locals. I felt safe all the time. The wifi was very fast and the place felt big enough for the 3 of us (two adults and one baby).
We travelled with my 14month baby, so the futons upstairs worked really well for us. The only complaint I have is the cleanliness of this place. Because I'm with my baby, I had to wipe down all the floors since he's always crawling and sitting everywhere. I wiped down a lot of hair and dust on the first day we arrived to the airbnb. Also lots of dust around the kitchen area. When we put out the futons, there were also hair on it that didn't belong to us. Other than the cleanliness, this place and the host gets a 5 star!
