Dear Mr Max Mustermann
Thank you for recently sending your application with regards to an internship position at "Name of the Hotel".
It was very interesting to read your application and learn of your career experiences so far. Unfortunately, each year we are inundated with request for internship and training however we are a very small hotel on this occasion, we are not able to assist with your requests.
May I take this opportunity to thank you for the interest you have shown in "Name of the Hotel" and to wish you every success in finding a suitable position.
"Team Name of the Hotel"
