I think this is a great thread as what is being judged is more than just the product, however amazing, but almost more the essence of a place. I choose Feltrinelli because despite visiting many many superb properties much more recently since (including several Aman's - Amanpulo twice in the last year alone) the place that immediately jumped into my head and stayed there throughout my internal thought process was Villa Feltrinelli although it was 6 or 7 years ago that we went there.

I remember a feeling of ease, relaxation, reflection and of course utter, utter comfort and beauty of surroundings during our stay there that can make me feel at peace just thinking about it now all these years later! Now it may have been circumstantial, connected to the timing of my trip there (for example my visits to Amanpulo have always been with children in tow and whilst i love holidaying with them it is never as relaxing as those pre-children trips!) so i guess i'll just have to get back there soon to test that out, but something about that property just makes it stand out amongst many jewels as THE hotel for me!
