Hillary's place proved a great base for our week long holiday in Mayo. The house itself was beautiful and spacious and our two young lads loved the upstairs living/playroom.
The area is wonderful. The quiet roads around the house are perfect for walking/running, with great views, and the town of Louisburgh is only a couple minutes away. Good shop there, a Spar out the road at petrol station as well, lovely book shop in town and a number of pubs and cafes.
Things we did while in area that we would recommend include canoeing at the Delphi Adventure Centre in Killary Harbour (the only fjord in Ireland - wonderful scenery), visiting Kylemore Abbey, cycling the Greenway (would recommend booking bikes in Newport and heading out towards Achill if you have kids), the activities at Westport House and playing splatball at Westport Adventure Park, as well as visiting some of the lovely beaches in the area. In truth we ran out of time in terms of doing everything we wanted to do.
Would highly recommend this as a venue to base your holiday in the west of Ireland.
