Beckett Locke is a great place to stay while visiting Dublin! The staff was kind and accommodating. We arrived slightly early in the day after a long flight and they stored our bags for us and got us checked in a few hours early. They answered questions on WhatsApp quickly and brought us towels and laundry detergent when asked. The place itself is nice and modern with a comfortable bed. We loved being next to the Red Line which made access to downtown Dublin easy.
One thing to note if you have a car—parking can be challenging if there is an event happening at 3Arena next door. Our first night we found parking easily but the second night the car park was full and we had to park a 15-20 min walk away.
