Hilton Garden Inn Dublin City Centre [was Custom House] {IRL}
Already has its own thread.
But yeah, its a very underrated property, great bar & breakfast, Diamond almost always in my experience gets early check in and rooms facing the Liffey.
Used to be a Jurys Hotel so quite different in layout from your standard cookie cutter HGI.
There's a bar around the back of it called The Harbourmaster which I highly recommend for pints, food and coffee.
