Como se dice - "We are so much alike?"
to say to a close friend...
Here is what you are expected to do for yourself.
Your question shows what you are trying to do. Please also show what you think is the correct answer. We are happy to help members who try to help themselves and show us their attempt. But, we don't want to do all your work for you.
After you show us what you think is the correct answer, someone will review it and change or edit it if necessary so that we are helping you to help yourself.
Please stick with us. This can work out for you and for us.
Nos parecemos y nos llevamos bien- We are alike and we get on well together.
(Nosotros) somos tan parecidos.
That translates to what you wanted... We are so much alike or we are so alike. Hope this helps.
HI Carlo, why not try yourself first, good practice
