Darach's place is very spacious and located practically just outside of Dublin -- a walk to the train station takes around 12 minutes, and there is a huge supermarket on the way, open until late. (A local acquaintance told us that there are some relatively nice places to eat in Donabate, but we never managed to try any of them because we'd spend our days in Dublin.) You check in via a keybox, just make sure to get the code from Darach in advance of your arrival.
There are three bedrooms in the house and a very generous number of toilets/bathrooms, so even a large group of guests would be absolutely happy, unless it included someone with a heavy disability, because all the bedrooms are upstairs.
The dishwasher simplified our life after a few other locations that lacked it, and having a washer and dryer at our disposal was also a bonus. The wifi signal is strong and stable -- a relief after some other places. There is also a little piece of lawn in the yard, where you can send the smokers of your party.
We can recommend Darach's place as a base for day trips in Dublin itself and in the vicinity.
