4/5 stars overall.
Location was good, only 5ish minutes walk to Otsuka station which is on the JR line, so you can use your JR pass.
Plenty of local restaurants, stalls, and stores.
2 minutes walk from a local supermarket.
2 minutes walk from a laundromat (the airbnb had a washing machine but no dryer so we took our clothes to dry there. 100 yen per 10 minutes)
less than 10 minutes walk to Nakiryu (michelin star ramen)
apartment was smaller than expected but was fine because we spent most of our time out and about as tourists.
The reason i gave a 4/5 instead of a 5/5 stars, was because the slats of the bed kept moving and falling off.
There is nothing worse than sleeping and in the middle of the night, the bed falls apart.
It was even nerve wrecking to sit on/ sit up from the bed as we were scared that the bed would cave in again.
I believe the bed slats need to be screwed onto the frame.
My husband, young child, and i ended up sleeping on the floor sofa bed and futon.
