I stayed at Justen & Andressa's place for the entirety of my six-day visit to Dublin. Highly recommend it as a decently priced spot near to the city center. Their place was clean and organized, the shower worked well, and having access to the kitchen was a great addition. I found the mattress and pillow to be super comfortable. The hosts are friendly and totally respectful of their guests' privacy. Only downside is the building is on a pretty busy/fast street, so you'll get a bit of noise, but unless you're really sensitive to sound, it shouldn't bother you. It is the city, after all.
