Just stay here. If you’re on the fence, you probably have two concerns: (1) distance from city center, and (2) what’s the set up like in the shared house.
(1) Public transport in Dublin is extremely accessible, and you can take the bus or green line from Patricia’s to the city center and back. It’s easy getting to the stops and buying the tickets, and helps you see more of the city. A testament to how easy it is is that I was able to do it without issue.
(2) The set up is as private as they come. If you don’t want to have interactions, you can slip in and out of your room with no problem. Or if you want to get to know Patricia, she will practically make it feel like your home, and invite you down for tea and pie, and chat for as long or as little as you want.
If either of these are your concerns, rest assured they are no issue and you should just stay here.
