This place is the best location you can choose to explore Dublin - located at Ha'penny bridge you will walk ou need to be everywhere within 5-15m (Trinity, Temple Bar, Guiness Stockhouse, St. Patrick Cathedral...). There is a tram stop nearby that takes you places (e.g. if you want to get to Howth or Phoenix park), as well as lots of shops, coffee places, pubs, breakfast places...
The place itself is cozy, very good shower, equipped kitchen, 1 bedroom and 1 extendable bed.
The heating system is pretty out-dated and complicated to deal with but the hosts took great effort to resolve everything within an hour.
The hosts are responsive and there were no problems with check-in or check-out.
