Great location! 2 minutes from the 747 bus stop coming from the airport and in walking distance to all major sights in Dublin (10-25 min walk).
Check in was easy and worked out well.
The room itself was very humid and we had to keep the window open at all times. The bed (which was more an unfolded sleeping sofa) felt worn out and wasn't really comfortable.
Overall it was okay, I wouldn't stay there again.
