We (two adults, two boys aged 9 and 5) have spent nearly two weeks at Jim's place, and it's been nothing short of fantastic!
The estate is beautiful, tranquil and really well kept. The rooms are spacious, clean and lovely. Beds were made available for our boys so that we could stay together in one room, which comes with its own bathroom.
It caters for all needs, including fridge and shelf space for self-catering, use of the house's fantastic kitchen and equipment, in- and outdoor space to eat, a comfortable (and beautiful!) living room with TV, and much more.
There's ample and safe space for kids to play in the gardens around the house, which our boys enjoyed greatly.
Jim, the owner, and his daughter Jessica, are lovely people! They are super helpful and just great to have around.
A taxi ride into Maynooth centre costs around 10 Euro, but it is also very nice to walk, taking just under an hour at a comfortable pace. We didn't hire a car but walked, subscribed for GoCar, called for the occasional cab and used public transport (e.g., to visit Dublin, which is very well connected with Maynooth).
Maynooth itself is a lovely town, and there's plenty in and around to visit.
Highly recommended!
