Welcome! One of my good friends lives in Germany...and none of you are as bad at English as you think you are! I am a little too lazy to look up the conversion from U.S. dollars to Euros but around here most places charge about $45 an hour, if you look hard enough you'll find some barns that only charge $25 maybe. If you look for ads and ask around you may find someone whose horse needs to be ridden and they will let you for free or for a small fee. Leasing/loaning is sometimes inexpensive as well, and lots of barn owners will let you work at the barn to lower the price. You will have to ask around because that depends on the person. Good luck!
