I was going to say Palazzo Naiadi in Rome but just remembered it is no longer part of Marriott...wow, we had a beautiful upgraded suite there. I really love the Shelbourne in Dublin. It is a classic, elegant hotel - perfect for its location on St. Stephen's Green. While we had an absolutely fabulous upgrade to the Bowmore Suite at The Glasshouse in Edinburgh, I cannot recommend it. Too many service (or lack thereof) issues. We've stayed at a lot of Autograph Hotels, in general, we really enjoy their uniqueness.
