We were two adults and one young child. Could easily accommodate a group of four.
Was nice having a hot shower, a kitchen with almost everything you needed, and a comfortable living room to relax in after some cold days out.
Perfect location to use as a base for exploring Killarney and surrounding areas. 10 minutes drive to Torc Waterfall, 5 minutes to Muckross house, and 15 or less from Killarney town itself.
Always difficult when planning to decide how long to be somewhere. We unfortunately only allocated two nights here and wish we'd had about four (for both the comfort of the apartment and to have more time in the area in general).
