Rents rose by over 10 per cent across the country in 2017.
New figures from Daft.ie show people in the city centre now pay on average €1,869 every month.
Across Dublin, rents are €4,500 more a year than they were during the peak of the Celtic Tiger.
Daft economist and Trinity professor Ronan Lyons says, unfortunately, the trend is here to stay:
"The dynamics in the market, with very strong demand and very weak supply, look set to continue for at least another couple of years so I wouldn't be surprised if we end up with ten years of strong rental growth in Dublin in particular."
