Hola, @Adelina_iulia and bienvenidos! I live in Baja, California - Mexico and am one of the moderators here on the Forum. Still trying to practice my Spanish daily while so many of the locals want to practice English 
My sister used to live in Madrid and I loved visiting her. Spain is such a diverse and beautiful country. While I enjoyed the wines there, I couldn’t get used to that late night dining - and that was when I was 20 years younger!
As for your experience here, not to worry. You will find many others who are new as well, and a helpful community to trouble shoot any issues you may come across. Above all is your love of travel and pets which is why we’re all in it together.
I noticed from your listing that you haven’t yet included your profile which can help others know more about you and your services. Here is a link: How to add a listing or profile link to your FORUM profile
Also - it might be helpful if you include the English version of your description right below the Spanish version. Just cut and paste the following if so desired:
I am 23 years old and I live in Madrid. I like to travel and sometimes I don’t have anyone with whom I would like to try this experience, apart from that I love animals.
We look forward to seeing where you go and any positive adventures you’d like to share. Recuerdos! (Best wishes:)
