TL;DR: Great place for the price, especially if you're just looking for a good view and a place to lay your head after sightseeing.
Pros:
-Location, location, location. The apartment looks directly out over the River Liffey and allows for convenient access on foot to most of the city's attractions.
-Easy check-in with a code.
-Affordable.
-Nice shower.
-Good wifi and a desk in the corner for digital nomads.
Cons:
-Some minor details, e.g. burnt out light bulbs, a window shade that was stuck in the down position, the carpets evidently hadn't been vacuumed recently, and the automatic bathroom light illuminates the entire place for a few minutes if somebody uses the toilet/sink in the middle of the night.
Just a few details that lowered our score from an A+ to an A. None of the cons were major, and we'd happily stay here again.
Check in instructions came via Air BnB message from the host at roughly 14:00, and there was no option to drop off bags early. If you plan to explore a bit before getting settled, you'll want to look up "left luggage" in town (5€/bag/day in the place we found on Lower Gardiner St).
