My parents and I stayed at Orla's place when we were in Dublin and it was excellent. Orla was an amazing host. Very responsive and accommodating. She went out of her way to get us acquainted to the city and gave us some good recommendations for things to do.
The house is in East Wall, a quiet neighborhood in the northeastern part of the city. It's a 10ish minute walk to a nearby tram station which will take you pretty much anywhere. Its also pretty cheap to take a taxi if you're not near a tram station.
The house itself is older (built 1892) and it has charming and cozy feel to it. The bedrooms are pretty spacious and the beds were wicked comfortable.
Overall it was a great experience and I couldn't have been happier.
