My family came to the Westin Dublin and had a fantastic experience from their staff. Over the years, I have stayed at many SPG properties worldwide, yet was very impressed at the level of care the staff took towards my family to make sure we had the proper room and care. 2 times we were moved (with our consent), to make sure our needs were met.
The location of the hotel is also fantastic, right near Temple Bar, the center of Dublin. Great food nearby (Klaw was our tops), and pubs. Concierge can help you reach all the hot spots via cab: Guinness Brewery, Teeling Whiskey Distillery, Kilmainham Gaol Museum/Prison.
Maybe it's the culture in Ireland, maybe it's something else. Regardless, I really felt it was a much better experience during this stay at an SPG property here than I've had in a long time.
