I and three friends stayed here for a weekend break - we chose this house because we wanted somewhere quiet, with easy links to the city centre. We got all of that and more! The house itself is comfortable and obviously well looked after within easy (read: 2 mins) distance from a local TESCO and friendly pub. It's also in walking distance from the Botanical Gardens - although unfortunately we ran out of time to visit those!
The buses are frequent and easy to use.
Also, Joan herself was so helpful from the beginning in giving advice on buses and travel. She made things very easy for us, and all together made for a wonderful visit to Dublin.
