Great location - just a few little things keep this from a 5-star rating
Beautiful hotel! Service was impeccable - everyone was so friendly, starting with check-in experience, including all housekeeping staff...
Just a few things that keep this hotel from getting 5 stars.
1. It's a bit worn. Yes, it's an old hotel and it's definitely charming, but a bit more attention to detail would bring this up a bit in the ratings. Blotches on the wallpaper, cracked tiles in the bathroom...
2. Missing towel hoop in the bathroom. Saw a chrome "blob" on the wall. Spied a chrome "hoop" under the sink. Put 2 and 2 together and realized the hoop should be fitted to the blob to make a towel hoop. 
3. The iron had a scorched soleplate that exactly matched a scorched spot on the ironing board cover. Luckily, we had dark-colored clothes to iron, but would have been leery of ironing lights with that. I'm sure the scorched discoloration would have transferred.
4. Yeah, this is petty: We had no "do not disturb" door hanger for our room.
That said, the property is in a great location. We slept VERY well, and the bed was comfy. The hotel is amazingly quiet - we rarely heard even hallway noise.
The maze of hallways is intriguing! The elevators are nicely divided among floor groupings. Unfortunately, we arrived too early to get our preferred room, and were on the 12th floor; these elevators are shared with convention services, so we were quite often delayed by stopping for those attending meetings and traveling between floors 4 and 7. 
Spent our two nights trying desperately to rationalize a 5-star rating on Tripadvisor, but settled for four. It could honestly be better. And it could be a WHOLE lot worse!
