Read the letter and choose the correct options

Dear Mr and Mrs Sanders,

I am writing to thank you both very much for your kindness during my stay at your apartment in London. You made me feel like I am a part of your family. It was a wonderful experience which I am sure I will always remember.

My room was very comfortable and the meals were delicious. During my stay it became possible to improve my language skills and I appreciate your support in helping me practise speaking. I have never thought that I will be able to speak English so well.

My parents send their regards and ask me to tell you that you will always be welcome guests if you would like to visit my country.

Thank you again for your kindness. I am looking forward to hearing from you soon.

Best wishes,

Roger Sammons
