Tenant Stefano, 24, and his flatmate Gino, of the same age, who are both Italian, said: “We threw a birthday party and invited about 20 friends, but they all brought other mates along and we couldn't leave them out in the street.

“The doorbell never stopped ringing and I was constantly busy serving drinks to everyone.”

Officers counted 135 partygoers in their late teens and early 20s in one flat.

And when they arrived after being called out by neighbours complaining about the noise at around 02.00hrs, they found the entrance hall stacked two or three people high and some fell out of the door when it was opened.

“We were terrified the ceiling would collapse with the weight of all the people inside,” complained downstairs neighbour Amparo M.

“The police counted 135. I couldn't believe it.”

Unable to enter the flat due to the sheer quantity of people in it, Local Police called for the tenant to come to the door.

“They told me off because we were disturbing the neighbours,” Stefano explained.

But he cooperated freely with the police and apologised repeatedly.

He turned off the music as instructed and called for his friends to leave in an orderly fashion and in single file – although many bore carrier bags filled with alcohol and soft drinks to finish off their celebrating elsewhere.

An apologetic Stefano says the police filled out a report form and he will probably face a fine for noise nuisance, but that his friends would help him to pay it.

“We've already spoken about it and everyone would chip in a bit of money, but I hope there'll be no need. We did what we were told when the police came,” he explains.

Most of the guests were studying in Spain on an Erasmus scholarship, although some were also Spanish students.

Neighbours in the block on C/ Vinalopó complain frequently of the revelry that goes on in the flat where Stefano and Gino are living.

“We're young, it's normal that we would hold parties,” Stefano commented.

“The other night we went over the top, but it won't happen again.”
