Dear Marcus,
It was such a wonderful surprise to receive your email earlier today! I have thought about our time in Greece quite often over the past year, so hearing from you really made my day.
Since you will be in the region for business in a few months, I insist that you stay at my place instead of a hotel. My spare room is comfortable and quiet, and it would be fantastic to catch up properly without the pressure of a vacation schedule. You are more than welcome to make yourself at home for as long as your trip lasts.
Regarding our time together, I have plenty of ideas. If you have a free evening, I would love to take you to that new riverside bistro downtown, which serves incredible local cuisine. If you manage to get a weekend off, we could also drive out to the coast for a hike; the views this time of year are absolutely breathtaking.
Do let me know your exact dates as soon as you have them confirmed. I am really looking forward to showing you around my hometown.
Best wishes,
Julian
