Appendix in LaTeX

I have the following document:

documentclass[11pt,a4paper,twoside]{book}
 usepackage[spanish,activeacute]{babel}
 usepackage[titletoc]{appendix}

 begin{document}

  setcounter{tocdepth}{2} 
  setcounter{secnumdepth}{3} 
  tableofcontents

  chapter{First chapter}

  begin{appendices}
   addappheadtotoc
   appendixpage
   clearpage
   chapter{Some name}
   label{label1}
   blah blah
  end{appendices}

end{document}

this gives in the ToC:

Apéndice Appendices....................60
Apéndice A. Some name..................63

and in the body of the document:

Appendices
(page skip)
Apéndice A
Some name

blah blah

1. The TOC shows "Apéndice Appendices" and I need it to show "Apéndices" (note the “s” at the end of that word; it’s not the same word that the first one currently in the TOC) Also in the body of the document it shows "Appendices" (in english) and I also need it to say "Apéndices" (in spanish), ie: the same word that should be displayed in the TOC. This looks like a babel issue to me.

2. Is there a way not to have to give each appendix a name? This is done with the chapter{Some name} command, but I’d like the name of Apéndice A to be just that: Apéndice A. This way the ToC would look like (assuming the 1st point is fixed):

   Apéndices........................60
   Apéndice A.......................63
   

   and the body of the document:

   Apéndices
   (page skip)
   Apéndice A
   
   blah blah
   

   Is there any way to do this?

I think a hack to accomplish the 2nd point would be to combine @murray’s answer with not giving a name to the chapter. This is, this line chapter{Some name} would have to be replaced by:

chapter[]{}

It’s not pretty but I think it gets the job done.
If anybody knows of a more elegant way to do this, please let me know.
