We stayed in Dave and Ann's house for a week with our four young children. It worked out very well. The house was great with lots of space for everyone and it was particularly nice that there were a few different living room spaces where different people could do different things, including a playroom with a variety of toys for the smaller kids.
The outdoor space is lovely. There is a very nice deck with a barbecue and fire pit as well as a nice bit of lawn. Because the whole property is gated we felt very comfortable letting the kids run around as they liked.
We also took advantage of the wide range of DVDs in the house when the children needed to wind down or when we wanted a quieter evening.
What is probably Ireland's most upscale mall is a short walk away and there is a wide range of restaurants and bars there that would cover pretty much any kind of food you would want. We didn't go into Dublin proper (we were visiting relatives) but there is good public transport close by as well.
Dave and Ann welcomed us warmly with a clear description of how to use everything in the house and with a variety of foods to tide us over for a day or so which meant we didn't need to worry about getting to the shops immediately.
Overall we had a very nice time and would heartily recommend this house if you are looking to stay in the area.
