This is absolutely the most perfect location for a vacation in Dublin!
After Dublin, we went to Doolin where we ran into a multi-generational Irish family's re-union. We were told, "The Cobbleston Pub is the best place for traditional Irish music, not just in Dublin, but in all of Ireland." The Cobblestone is literally 100 meters/yards from this apartment.
Jameson's former distillery site has tours, drink-making classes, and cask tastings - and also less than 100 meters/yards away from the door. The Luas stop is a very convenient way to get around Dublin and just as close.
Guinness Storehouse is a 15 minute walk. If you're into over-priced drinks and crowds, Temple Bar area is 15 min walk away. The Kilmainham Gaol is similarly close. You'll want to use the Luas or a bus to get to Trinity and see Book of Kells, get the boat ride to Howth, and visit the Emigration Museum, but it's still very convenient.
In addition, there are a few good breakfast and takeaway places on the Smithfield plaza that can help you jumpstart your day experiencing all that Dublin has to offer.
So while this apartment has cool little balconies all around it and a sizable dining room area, we had no interest in lounging around the place... there is so much to see and do in Dublin, that we pretty much ignored every amenity in favor of being out on the town. For us (5 adults), this was a spacious crashing and rallying spot to explore all that the city has to offer.
