Cork is the second largest city in Ireland, so the consumption is a little higher than other cities, but not as expensive as Dublin. Because the whole country of Ireland is very expensive, the landlord has to adapt when he comes. The cost of living in Cork is 6-7 W a year. Of course, this figure is the cost of your normal life. If you still want to go out to play, the cost of shopping is not enough. Mainly because many things in Ireland are imported, so they have to pay taxes, so the prices are high. Potatoes are the cheapest food here, so the landlord should be prepared.
Ireland has nothing to do with it. It is just a rural area with a good environment. It is suitable for reading and quiet, but there is nothing to play, and the quality of the people is not high. Also, you should be able to adapt to the windy and rainy weather here. I hope the landlord will think it over.
