*bump*
Last weekend we stayed at the Shelbourne and it was one of my better Marriott experiences ever. I had also read the epinions saying it was a bit dingy and faded, but we decided to give it a shot anyway.
Upon arrival, we heard my favorite words "Due to space availability, we were able to give you a complimentary upgrade Ms. Grendelyn."
We had a huuuuge room with high ceilings on the second floor that looked out on St Stephen's Green. There were complimentary chocolates and a Shelbourne paperweight (what an odd gift??) to welcome us. The toiletries were divine, not the usual Neutrogena sludge. The turndown service included yet more chocolate, spring water, and a triple shot sized bottle of irish whiskey. Apparently the first night there was some confusion about how many were staying, and the second night's turndown service included more whiskey and a mini-bottle of Baileys. I was very amused at the idea of his and hers night time beverages.
The bathroom was huge and clean with double sinks and a powerful shower. The staff could not have been kinder, dispensing directions and umbrellas.
There were several charming restaurants in the hotel, but we opted for a pub meal Friday, light dinner at a wine bar down the street Saturday evening (highly recommended) and Sunday lunch at Browne's (in the next building from the Shelbourne).
Marriott has clearly invested a lot of money in renovating the Shelbourne back to its former glory, and with great success. Overall, very highly recommended.
