Dear Sir or Madam,

I am seventeen-years-old Spanish student. I am coming to London

in July and I would like to attend your school and improve my English.

Could you tell me how I can register with your school?

Could you tell me if/whether there is a space for me?

I would also like to know how much it costs. I do not have anywhere

to stay in London. I would like to know if you could arrange accommodation

for me.

I look forward to hearing from you.

Yours faithfully,
