We spent a week at Iso's place. The couch is very cozy and the bed is super comfy, and the building feels safe. The rooftop has a nice view, though it was sometimes randomly locked. It's on a busy main street so there's a lot of traffic noise with the windows open (and in the warm weather, it was important to have them open), but that's a fair trade for the great location! It's central but in a less touristic neighborhood, with lots of good coffeeshops etc in easy walking distance. The wifi was solid, and the space was clean, though a bit worn. Having a washer/dryer was also appreciated. Overall it was a good value in Dublin!
