Your description of the left luggage facility makes it sound like left luggage is just piled up unattended in the middle of the floor in the middle of the airport! The left luggage facility is on the ground floor of the short term car park atrium. The short term car park is just across from the terminal building and the left luggage facility is on the left, just pass the lifts/elevators. It's about a minute's walk from the terminal. It's a secure room with a staffed counter which is securely locked up when not staffed. Items stored in the facility are indeed monitored and can't be accessed by passers by. We've never had cause to use it ourselves as we live close to DUB but we would have no problems either using if we needed to or recommending it to others.
You really need to get in touch with the left luggage facility directly yourself to check out their charges as it you will probably need to given them a description of what you plan to leave there to get a price from them. You can also ask them about security. If you are in Ireland at present and don't have a phone, why don't you use a public phone or a phone at your accommodation? You can also make Skype calls from Internet cafes

The Store It facility recommended in the previous post is a long way from DUB and not that easy to get to by public transport. Dublin Airport is in the northern suburbs, while that facility is in the western suburbs, about 18km away. If you want to check out similar facilities, this one is much closer to DUB (about 10 minutes' drive).

Other than Busaras, the bus station, where the left luggage facility is likely to be very secure, we'd take our chances with the airport facility if the price is right. You might also want to factor in the added convenience of leaving your stuff at the airport rather than in the city centre or elsewhere.
