Yes, but that isn't who is connecting, that is who is mounting the
share.
You should be mounting the share as I known user.

This is where it goes really pear-shaped, you have made the guest user
'andrea' (who presumably has a password and isn't 'urca'), this is
somewhat akin to using 'valid user = andrea' in the share and you
cannot use 'valid user' with 'guest ok = yes'

Just remove the 'guest account' line, it will then use your OS's
guest user, probably 'nobody'

Just mount the directory, that you want to share, with a known user
and then connect to the share, via Samba, with a user that is unknown
to Samba or the OS.
