My best friend and I rented a car and toured the whole of Ireland. Dublin was the last stop on our itinerary and having a clean, quiet home to retreat to after exploring the city center was fantastic. Sean and Aisling's place is spotless, modern, and has everything you need to be comfortable. There are great pubs and restaurants within 5-15 min walking distance.
We used the MyTaxi app for rides to attractions. Kilmainham Gaol was a 20 min ride for about 15 euros and the National Museum for Archeology was about a 15 min ride for 13 euros. Parking for our eco car on the street was no problem.
Sean and Aisling were prompt to reply to any of my questions. They were kind enough to be flexible with our check in time, which allowed us to freshen up after a long drive before sightseeing and dinner in the city center on our first night. I would highly recommend their home.
