We really enjoyed our stay here. The flat is very nice -- stylish, has a kitchen and TV, and very cosy bed! Location-wise, it's pretty central -- very near to O'Connell Street (a main street in Dublin) and there's a nice park nearby.
Everything was automated; we received a message with a passcode into the building and retrieved our keys from a "KeyCafe" (box on the wall where you enter a booking number and retrieve a keycard). All of this was done with no hassle. We also requested an early check-in which was accommodated.
