Gardiner House Hostel had a mistake in our registration on their end, and we ended up having to pay an extra 75 euro because of their glitch on their end - there was no effort on their end to comp the difference even though it was their mistake. The main eating area was sticky and not super clean, and many of the hallways were rather rundown and gross. My room had been recently renovated, so it was clean and beautiful, but smelled strongly of paint fumes the entire time we were there. There was loud music playing in the hallway at all times, and at least in my room, the main overhead light stayed on all night and the light switch didn't work to turn it off. The staff was friendly and kind, but in all honesty, the hostel was kinda like they put lipstick on a pig. Not a great stay!
