I have stayed at Glenbrook House on two occasions with my son.
Eileen is a wonderful host who instantly makes you feel welcome and will keep you supplied with cups of tea and biscuits during your stay. She can advise you of local attractions and where to eat. The rooms are very clean and comfortable, there is also a cosy guest lounge. Breakfast is lovely. 5 mins drive from Kerry Airport.
We have stayed with Eileen twice and will definitely book again, Glenbrook House is just how a B&B should be.
