Hotels have been criticised for hiking their prices for the night Liverpool is due to host the Eurovision Song Contest on behalf of Ukraine.
Metro Mayor Steve Rotheram said some have "jumped at the chance to grossly inflate prices" and called for a "measure of self-control".
According to the Liverpool ECHO, prices have shot up at hotels, guest rooms and other accommodation venues across the city.

A look on Booking.com shows multiple single person rooms being priced up for well over £1,000 for the night of May 13, 2023, when the song contest will be held in the city.
The mayor said: "During one of the turbulent years our country - and our continent - has faced in decades, Eurovision is a welcome distraction for millions of people who will be looking forward to celebrating a global gathering in Liverpool on behalf of our friends in Ukraine.
"For many visiting us next year, it will be a once-in-a-lifetime opportunity to make memories at an event that promises to be a special occasion for those present and for the millions watching at home.
"For our area it is a fantastic chance to showcase all that is good in a great city - and beyond.
"Eurovision is supposed to be an occasion where everybody comes together in the name of peace, love and understanding. It is a multi-coloured, multi-cultural spectacular.
"That is why it is so disappointing to see some businesses in our region, who have jumped at the chance to grossly inflate prices - with some even cancelling existing bookings, only to re-advertise the same thing at many times the previous price.
"Before the pandemic, the Liverpool City Region's visitor economy was worth £5bn a year, welcoming 67.4 million visitors and supporting over 57,000 jobs.
"During and after the pandemic, we helped to support the local economy and kickstart its recovery with almost £200m of funding, much of it specifically targeted at the sector.
"Eurovision offers us the chance to electrify that nascent recovery and turn it into new growth.
"I understand how the hotel industry operates and that demand will be unprecedented- but there must be a measure of self-control to this decision.
"I've called this behaviour out several times before, especially when football fans have been ripped off for flights and accommodation.
"I do not want anybody to be prevented from visiting our great city region because it has been made financially restrictive.
"I'll be speaking to political colleagues about our response and will make representatives to the sector in the coming days.
"Hopefully it won't be too late to come to a resolution that ensures as many people as possible are able to come and experience Eurovision in our region".
