Stayed here for a weekend, it was lovely. Didn't meet Dean but he was easy to get a hold of before my trip to work out details. Mario showed me around and he was great, told me everything I needed to know about the place. Even let me check in early which was wonderful! The room was perfect and the bed was comfortable. I didn't see Mario after check in but he was easy to contact if I needed anything. I walked to the Guinness Storehouse from here and all around the Trinity College area, even far beyond that, good location. This was a perfect place to stay since I spent all my time exploring Dublin.
