Great place to stay. Everything is very well organised and the interior design is aesthetically pleasing.
Buy a pair of earplugs from the front desk, you will need them when sharing a room; most backpackers could care less about the noise they make when others are asleep around them, and Gardiner Street stays active at all hours.
Bathrooms and toilets were very clean. Both showers I used had cold water taps disabled so the water was uncomfortably hot. Lower level toilets were all clogged. Kitchen was clean but all fridges and storage compartments were packed full.
Cooking cut-off and silence times are not adhered to.
I was grateful that reception allowed me to store my suitcase free of charge while killing time before my flight out of Dublin.
