Rachel was a wonderful host. She met us at the apartment and explained how everything works and described lots of things to do in her neighborhood and all around Dublin.
The apartment is large and was very comfortable for my family of 5 and it can easily fit 7. We walked everywhere from there and the DART train is just down the block for excursions north to Howth (highly recommended, we loved it) or points south. The town of Ballsbridge has some very nice restaurants and pubs. Plenty of cabs or busses if you don't feel like walking into the City Center.
We highly recommend and would definitely would stay again.
