The apartment is a really nice space - cool loft style bed above the living area, well equipped and laid out. Nice decent second bedroom as well. Everything is in good shape. Communication is clear and quick and it's good value for a city centre Dublin place.
The location is super convenient for the city centre. You can be crossing the Liffey (centre point of Dublin) in 10 mins walk or 20 mins to get onto the train line. We didn't use the buses but they were constant too.
The area has lots around it - there's a Spar convenience store and bars/cafes. It's a bit rough and ready but always felt safe to us.
The only drawback for us was there was a lot of noise from other apartments. First night it was a party next store, other evenings it was people coming in in late and making a lot of noise. The road noise is significant too. If the noise doesn't bother you, then it's a good place.
Small extra point - the double in the main bedroom is small and a bit old.
