Amazing location! Almost everything was within 10 minutes walking distance. There is a bit of street noise (mostly people yelling), but it surprisingly tends to die down pretty early, even on weekends.
The apartment itself was nice and roomy, with all the necessary amenities. Great shower, as well.
The only minor downsides are that the bathroom absolutely reeks of cigarette smoke and that the curtain in the bedroom isn't light-tight in the slightest.
All-in-all: probably the best you'll find on AirBnB in Dublin.
