We recently stayed with Grace and Ian in their house in Maynooth and had a very pleasant stay. Greeted with a cup of tea and biscuits on arrival we had a nice chat with them before heading out for some food. The location is ideal,a few mins walk from the train station and town while Maynooth has plenty of nice restaurants and bars to offer. Grace and Ian also gave very helpful info about places to eat or drink in town.
There was a substantial continental breakfast each morning which sets you up nicely for the day. The location is a perfect base to visit Dublin on the train which is quite frequent or as was our case on the Sunday to Visit ikea.
I would definitely recommend a stay in Grace and Ian's place for anyone wishing to visit Dublin while avoiding the frenetic pace or prices of Dublin or just to see Maynooth itself.
