For extened stay would need to take a few extra kitchen items, spices, foil, oil ect. The name is "old", however very much new housing estate on outskirts of killarney, good set up for groups or family rather than couple get away compared to other cottages we have stayed at. Not sure how warm it would be in winter, open design and no carpet downstairs living room.
Location is a few minutes drive from Killarney centre although traffic crossing city can be terrible at times towards ring of kerry drive. We stayed in No 14. Cute cottage, fire place, heaters, comfortable bed and wifi works well, kitchen equiped with fridge, stove, oven, microwave, dish washer, pots ect. Friendly pub within walking distance, open late, serves food, irish coffee and sky sports. Not hard to find.
