Hi Mika,
I am writing to thank you for making my recent holiday in Japan such a great and memorable experience.
Your ideas and attention to detail allowed me to get from place to place with a minimum of fuss.
All your accommodation places were very convenient to stations and the tours you selected allowed me to get a good understanding of the local sites.
I have already given your details to some colleagues.
Again Mika, thank you.
Regards,
Brian
