Recommended Temple lodging near Mt Koya

My brother and I are planning to go to Mt Koya sometime during the year and we want to experience lodging in a temple. I wanted to ask if there's a reservation site for lodging like this, since the English sites like booking.com and agoda have very limited choices. Even Japanese-only lodgings and sites are OK since my brother and I can speak and read at a workable level. If anyone can recommend a specific temple, that would be great!

Sadly, they do not have any contacts with Koya. But may used for other places nearby like Shirahama, Ryujin, or Katsura.

There are many options. You can use Google Maps to scry the area. Find any temple you think has a good location, and google it. Some of these places may need direct email for reservation.

I booked thru this official Koya San site and was able to tell them my budget and vegetarian food requirements. They even called me in Australia to confirm everything. Highly recommended

My friend and I stayed at Ekoin. Their website is in English and the monks speak English too. It was well placed, about halfway down the main road, and right near a bus stop. Comfortable, food was good, beautiful interior garden and the onsen was lovely. We were also given souvenir chopsticks!
