If you are planning to visit Arashiyama and you have a baby or kids in tow, I highly recommend to stay at least 1 night!
The reason is that Arashiyama is SO crowded, that I guarantee you will enjoy it much more if you stay overnight and have time to relax and enjoy this lovely town in the morning and evening when it is not crowded.
Most tourists go to Arashiyama for just a day trip (from Kyoto), so if you stay overnight, the mornings are practically empty if you go out around 7-9am, and the evenings are also quiet after 6pm as most of the restaurants and shops close early at around 5pm.
I chose this hotel because of the view!
It has an amazing view of the river and gorgeous Japanese style lounge, bedroom, as well as a Japanese hot spa.
