This reminds me of the time when I received a call during my stay at HR Etoile in Paris asking me how my stay was (during renovations). I provided some comments about the RC closure and substitution. Next day I received a message from hotel GM's assistant asking me if I were available to meet with the GM for a drink. Mr. Morauw (who was also the Hyatt France Region VP) and I had a great conversation and I provided comments about what I liked. Day after I checked out, I received an email from Mr. Morauw's assistant with a voucher for 3 nights at HR Etoile in a Suite! I returned to the hotel that summer with my wife and friends for 5 nights (I paid for 2 extra nights and suite was extended to the additional 2 nights) and my Suite turned out to be the Loft Suite (highest level suite at the hotel) with view towards Sacre Couer. I booked our friends' room and applied a DSU, and that was upgraded to a corner Executive Suite with view towards Arc de Triomphe and Eiffel Tower. We watched Bastille Day fireworks from our friends' suite. Best hotel stay experience for my friends.
I have returned to the HR Etoile every time when I'm in Paris ever since. I haven't contacted Mr. Morauw on my subsequent stays since I didn't want to bother him.
