Believe the reviews. This is a phenomenal place to stay in Dublin. From initial check in with the very helpful staff to entering my room, and being completely blown away by the quality, cleanliness and incredible value for money, everything about my stay was a very pleasant surprise.
The closest Airport Express bus stop is Aston Quay. It's the second stop on the route. Get off the bus, turn around, see the O'Connell Street bridge, walk over that, take the 2nd street on the left (Abbey St) and walk about 5 minutes to the Clink i Lár which will be on the left. Buses run on time BTW.
Simple easy check in, with helpful staff if needed. Get your key card and go to your room, but you will need to scan your card in the elevator. I booked a single room which was very reasonably priced for what you get.
I was on the 7th floor and had a good view over the city. The attached bathroom was amazing: modern, clean, lots of hot water and good quality fixtures and fittings. The bed was comfortable and there were plenty of outlets.
The location is close to plenty of places to eat, shop and drink. Sadly, Dublin is no longer the place it used to be. LOTS of shady characters, some unhoused and mentally challenged, intoxicated and under the influence people mixing with ordinary people. It pays, as in all big cities, to be aware of your surroundings and use caution.
Overall, Clink i Lár punches well above it's weight and I can't say enough good things about it. Highly recommended.
