I am writing to apply for the post of tour guide advertised on your website. I believe I fulfil all the necessary criteria, and very much hope that you will consider my application.
I have lived in this town all my life, and therefore know all about the places of interest and their history. I have visited the castle and the cathedral many times and I have read many guide books full of interesting historical facts. I therefore fell that I am in a good position to lead visitors around these sites. I have always been interested in history and over the past few years I have regularly participated in activities at the castle and at other sites.
Recently I have been working as a receptionist at a local hotel in the evenings. So I have experience of dealing with overseas visitors, and I enjoy talking to them.
I do hope you will consider me for this post, and I look forward to hearing from you.
Yours sincerely.
