My wife and I stayed here for three nights - Grainne promised that she'd try to get us some good weather and she certainly delivered!
Grainne and John are lovely people who were very approachable, knowledgable, helpful and were very pleasant to chat to. They didn't crowd us but we knew that they were there when if we needed them.
The place: The shower was lovely and the massive bed was so comfortable. The kitchen is very well equipped and we prepared a couple of reasonably complicated meals and found that there was more than enough utensils etc for good food prep.
Locationwise, Grainne and John's place is perfect if you enjoy walking and the like. (John is a runner and very keen to tell you about nice routes for walks/runs). Fore is a tiny hamlet/village but Castlepollard and Old Castle are nearby and you can get everything that you need there. Mullingar is about 20-25 minutes drive away. This is a great base for touring about.
If you are looking for peace and quiet, this is the place for you. I can't fault this place at all and Grainne and John's welcome made the trip for us.
Highly recommended!
