With zombie stilt walkers, a freaky fire stage-show, the Halloween Fiestaval was Lost in London's biggest event ever, with students from 46 language schools in London and at least six from outside the capital.
Most of the party-goers were in fancy dress and enjoyed entertainment as well as a night of dancing at London's biggest venue, Proud 2.
"It was just fantastic," said Tristan Bailey of Lost in London. "There was such a good vibe. Halloween is our biggest night of the year because it's such an international theme.
"We had three pythons at the entrance and I think everyone had their pictures taken with a snake. Most people were dressed up, and there were some fantastic costumes, including an amazing Mummy and lots of Jokers from Batman.
"Two makeup artists were there all night transforming people, as well as a percussion band and a beatboxer. It was great and we're getting lots of messages and emails about it.
"The only problem is how to make it bigger and better next year!"
