Hotel prices jumped by 7% in Derry last year as the city attracted an influx of international visitors following its nomination as the inaugural City of Culture.
According to the latest Hotels.com Hotel Price Index, Derry saw an 18% rise in visitor figures, particularly from Europe.
The increased demand for accommodation saw the average room rate go up from £60 to £65 a night. This contrasted with Belfast, which saw a 5% drop from £68 to £65 also.
Now in its eighth year, the index chronicles the actual prices paid by travellers in more than 142,000 hotels across the world.
Matt Walls, vice president at Hotels.com, said: “The award of the City of Culture for 2013 has given Derry a big boost and helped to highlight some of the fantastic attractions and events there, such as the mighty City Walls and the Jazz and Big Band Festival.
“However, the average room rate of £65, which is the same as that in Belfast, still offered outstanding value for the visitor and the weakened pound also helped increase traveller numbers from overseas.”
