Historic place, but you do pay for it
I read several comments about the great experience on the "gold floor". Well, maybe I was on the silver or copper or whatever other floor, but where was the service of this super great hotel?? The room itself was large and ok, with a huge bathroom, but lacking those details you find in some other 5*/luxury hotels. For instance, why was the TV so small and so far away from the bed, where was the free wifi customary in some 100-dollar-a-night hotels, why do they charge you nearly 20 dollars with tax for a mere bottle of water, while you paid 500 dollars for the night etc ?
Then the breakfast. Why would I have to argue for 10 minutes with the waiter because I wanted to seat at a 4-person table (yes, I admit I was on my own, but with a large newspaper) when there was no-one (yes, no-one) else in the large restaurant ?
But true, apart from that you are in a heritage place...... Is that worth the price? For me no. When I read that this hotel is worth going to because the bed is comfy and the breakfast is good, plus you have lobster rolls at cocktail time, I personally prefer to find another hotel with as decent beds and breakfast, but better attention to me and better value. And you are even not in the historical center.
