Hola Miguel, 

I haven't seen Ubeda yet, but it is on my list of cities in Andalucia to see. 

Presenting of Myself

I´m Miguel,  I´m a 34 year old Spanish man. I was borned in a precious, an monumental city of in Andalucia called Úbeda but I dont´t live there yet now/at the moment. Physically, I have am a normal height and a normal weight, I have brown eyes, and brown hair.
I consider myself a cheerful person, responsible and peaceful. I´m married, I have two children, a boy and a little girl of only 1 year old. [¿quien tiene 1 año? ¿Los dos, o sola la niña?] 
I´m a primary school music teacher, I´m a music teacher but now I´m working like as a primary´s tutor imparting with subjects like language, maths, science, arts and crafts... to children of ten years. I have studied teaching for my degree career but I have also studied piano´s in my degree career too. [Carrera and career are false friends. We say degree at university, and career after university (trabajo)] I play the piano too and sometimes I teach provide piano tutorials of it.

In my free time I like to listen to music, mountain bike, reading, but the best thing I like doing is to stay be with my family, and most importantly, with my wife and my children.

That's all!
Someone Could someone correct me?
Thanks a lot.
