The Sun reports that a couple and their young child were seen in the ground-floor flat, which has stood empty ever since Madeleine's disappearance.
A British holidaymaker, also staying at the resort, said they had seen a 'young family enjoying their holiday', adding:
'They didn't seem to have a care in the world, and if I hadn't known of the flat's history, I wouldn't have given it a second look.'
The flat is owned by retired Liverpool school teacher, Ruth McCann - who is not related to Madeleine's family. She had been trying to sell the two bedroom property, but took it off the market due to lack of interest. It is thought she is now renting it out as a holiday home once again.
Madeleine was just three years old when she went missing from the flat in 2007 whilst her parents, Gerry and Kate, had dinner with their friends in a nearby restaurant.
What do you think? Would you rent the apartment? Or would thoughts of its unhappy history overshadow your holiday?
