We stayed with Teresa and her husband for three nights and were very pleased with our room and amenities. They are a friendly couple and Teresa was very helpful answering all my questions about transport options and places to visit etc.
The no 14 bus (frequent service) is a very short walk from their house which takes you into Dublin City centre in about 15min. We used a 72hr Leap Card on Teresa's recommendation which is really good value for money as you can use it on loads of different transport services, as often as you like during the 72hr period (purchased from WH Smiths in Terminal 1 for €16).
You can also use the Leap Card on the no 16 bus which goes to and from Dublin Airport to the city centre (about an hour) and is significantly cheaper than the Airport Coach busses.
We had a great stay and would highly recommend Teresa's home.
