I had a mixed experience at Gardiner. On the one hand, it's really great value. Dublin is so expensive, but Gardiner offers people on lower budgets the chance to enjoy the city, which is great. The breakfast is good, and the staff are all really lovely. However, I barely got any sleep the whole time. People did not obey the rules to keep quiet after 10pm, and I had to tell people to turn off lights at 11.30pm so I could sleep (which they resisted). The doors in the rooms make a really loud beeping noise whenever anyone uses their key card to enter, and this woke me up throughout the night, all the time, as I was near the door (and I'm not even a light sleeper!) I personally wouldn't stay there again, as I was so exhausted during my trip, due to the lack of sleep.
