The pictures make the air bnb seem big, however it is quite small and the roof is very low, (I'm 177cm and everytime I would walk though doors my head would skim the frame.) However, that being said, it is still a very cosy and convenient place to stay in, there are several shops in the vicinity ranging from Family Marts and grocery stores to small local restaurants.
This Airbnb is however located along a private railway line, meaning JR passes won't get you there, so you may need to account for some extra travel costs using an IC card if you plan on getting the JR pass.
Overall it is a convenient place, but costly to get to, the images are SLIGHTLY misleading but is without a doubt still worth the stay!
