Riding / grooming share

Riding / grooming share - Hello, I am looking for a riding/grooming partner for my 18 year old Hanoverian mare.
We are based in Goldenstedt/Varrenesch.
We have an indoor arena and a riding arena.
Nice small stable community.
Honey is a pure leisure horse.
With her height of 1.64m she covers well.
As she has been standing for a long time, she needs to be trained first, so no test riding possible.
In addition to moving the horse, your tasks will include mucking out her stall and preparing feed. Of course also stuffing hay nets.
Looking for 2 times a week
