We stayed here for six nights in a row. This place, at first, seemed fantastic. We were in the heart of city center and a literal ten-minute walk from everything (Temple Bar, Guinness Storehouse, St. Patrick's Cathedral, Trinity College, etc...). Places to eat were abundant nearby also. There's a bus-stop two minutes from the front-door in nearly every direction. I mean, your neighbor across the street is a gigantic cathedral! However, we quickly realized that once we got past the awe from its location, there were quite a few minor issues: 1) the front door doesn't quite fit the frame, so it's a bit of pain to close and open (took me a bunch of tries before I realized the trick); 2) the floors in the common area are warped and very dirty - we were wearing white socks and the bottoms would be black within half an hour just from walking on the floor; 3) there was no hand soap in the entire apartment so I had to go and buy some; 4) the shower drain wasn't draining well at all so the floor of the shower would flood; 5) there were holes in the walls of the shower.
Beyond the above, the place was definitely set up for travelers which was nice. There was a ton of information left for us and everything was clearly labeled with note cards. The common area was spacious and the bed, while very firm, was also decent. We originally thought the couch was a pull-out but in fact is just a very large couch which made for an okay bed.
