We stayed at the apartment for around 3 weeks and had a great time. Tateishi was a nice and calm place that had good access to pretty much every direction we traveled to. The hosts were extremely friendly and helped us out whenever we had troubles.
It helped out a lot that the toilet was separated from the shower and made our mornings a lot faster with three people. The place was very clean and easy to access. There is also a convenient store close to the apartment that is open all time around.
