I’ve got mail! What should I do?

Yesterday I wrote an e-mail to the manager of Best Western Hotel City in Milan about beeing treated badly by unhelpful staff. Here is the blog post

Today the manager replied. Here is his answer:

Dear Mr. Brosstad, 
I apologize for the inconvenience and for treatmen you had from receptionist. He is new in our hotel but, of course, it is not a normal attitude to treat guests in this way. This attitude does not respect the think of our hotel. 
I thank you very much for your advise so we can always ameliorate our services and our quality. 
I want to excuse very much again and I would like to offer you a week-end for two persons, as  my  personal guests in our hotel or a discount of 50% on the price you paid during your staying. 
Waiting for your comments, will you agree our best regards.
Best Western Hotel City
Omar Sozuer

So, what should i do?
