Translation of abmontieren

I have contacted you 12 months ago to propose your school's inclusion in our language school directory. I wanted to inform you that our site achieved high positions in search engines last month.
In South American we speak normal Spanish, but sometimes it sounds like music and not as you are used to it from the school books and video tutorials from the language schools that you have learned in Guatemala.
Do you like Hamburg? I've never been there. Maybe I can visit it one day. I hope to hear from you and please write me in German, so that you will also learn it. Do not worry about mistakes.
