Me and my boyfriend stayed at Patricia's place from 30th April till 5th May. We were mostly out discovering Dublin and few tourist spots around Ireland (we booked tours).
When you coming from the airport with the bus, apartment is not far from Railway station (5 minutes walk). Patricia gave us detail interactions where to go to find the apartment and also she let us in early in the morning, because we had an early flight.
Other attractions (like Guinness storehouse or Phoenix Park, Zoo) are not that far away, if you don't mind walking it takes you around 20 minutes to reach O'Connor street or you can take bus or tram.
Overall we were happy with our staying at Patricia's place.
