Translation of renoviert

I hope you could understand my last letter to you. You see, when I write in Spanish I am not very confident. I always question myself and each and every sentence takes about fifteen minutes.
The letter and the date are fine. Let me know how many people are interested. I cannot promise that it will work. The size however is OK. It is worth a trial, maybe even the ones with Spanish words.
