The location is spot on and ideally place for visiting Dublin. That said, there were a number of things wrong with the property:
1) The toilet in the en-suite did not flush properly.
2) The dishwasher was unusable as the compartment to put the washing tablet in was broken and wouldn't hold the tablet.
3) The wi-fi was unusable. It's all very well having its own Virgin router but there were no instructions on how to connect to it. The router only had an IP address and no network name.
4) The apartment needed maintenance - there was peeling paint, water stains on the wood work, the outside table was filthy, and one of the outside chairs was broken.
5) The sauna is pointless and unusable by more than one person. Putting it in the en-suite bathroom only makes it less likely to be used.
6) The apartment is on the third floor and there's no lift. Not your fault but that should be mentioned in the description of the property.
We paid a premium price for the apartment and got less than our money's worth. Until the problems are sorted I would advise against renting the property.
