Dear Sir or Madam,
I am writing to apply for the part-time tour guide position advertised on your website. I have lived in Istanbul for my whole life, and I would love to share my city with visitors.
I know the city extremely well. I have studied its history at university, and I regularly visit the old town, the museums and the less obvious districts, which many tourists never see.
I believe I would make a good guide. I am outgoing, patient and good at explaining things clearly, and I have two years of experience working in a souvenir shop where I dealt with visitors from many countries.
I speak Turkish and English fluently, and I have a good level of German and basic Spanish. Many of my friends are tourists I have shown around informally, and they have often said I should do it professionally.
I would be able to work at weekends and in the evenings. My CV is attached, and I would be pleased to attend an interview.
Yours faithfully,
Emre Yildiz
